What is Arrhythmia?
How do I sense it?

An arrhythmia is a problem with the rate or rhythm of your heartbeat. It means that your heart beats too quickly, too slowly, or with an irregular pattern. It can sometimes feel like a “fluttering” in the chest or can also be silent and have no noticeable symptoms. Many arrhythmias are harmless, but some may be dangerous and require treatment and effective management.

What is Bradycardia (or) slow heartbeat?

In most healthy people, the normal heart rate is 60 to 100 beats per minute (BPM). People with Bradycardia have a heartbeat of less than 60 BPM. Although a resting heart rate below 60 beats is considered Bradycardia, it doesn’t always signal a problem. What counts as an abnormally slow heartbeat for one person may not be the same for another. It can be affected by age and physical condition.

  • Athletic adults can have a heart rate below 60 BPM, and that is normal for them.
  • Your heart rate may fall below 60 BPM when you sleep but still be normal.

What is Tachycardia (or) fast heartbeat?

Tachycardia is a heartbeat above 100 beats per minute (BPM). In most healthy people, the heart’s fluid-pumping action results in a normal heart rate of 60 to 100 beats per minute (BPM). Sometimes a rate above 100 beats is normal. For example, when you exercise, your body needs more oxygen than when you are at rest. Your heart meets this demand by increasing the rate at which it pumps oxygen-rich blood to the body.

Other times, a heartbeat greater than 100 beats a minute is abnormal and is the result of a problem with the heart or the irregular electrical signals in the heart. If you have a fast heart rate, it could be caused by a type of Tachycardia.
There are several types of Tachycardia. They are classified by the part of the heart in which they originate.

What are premature ventricular contractions, or extra heartbeats?

Premature Ventricular Contractions are also known as PVCs or PVBs (for Premature Ventricular Beats). They are early contractions that occur when the ventricles (the lower chambers of the heart) contract out of sequence with normal heart rhythm. Although they are generally harmless and usually do not require treatment, PVCs may trigger more serious arrhythmias in people with heart disease or a history of Ventricular Tachycardia.

Premature ventricular contractions often cause no symptoms. But you may feel these sensations in your chest:

  • Flip-flops
  • Fluttering
  • Pounding or jumping
  • Skipped beats or missed beats
  • Increased awareness of your heartbeat

PVCs most often occur spontaneously; however, they can also be triggered by:

  • Caffeine
  • Alcohol
  • Medications (especially decongestants)
  • Certain medical conditions such as hyperthyroidism, anemia, hypertension and stress

Diagnosis of your arrhythmia

When you visit a doctor to discuss your arrhythmia, be prepared to talk about your symptoms, how long they last and what they feel like. The doctor will want to know your medical history, in particular about heart or lung problems, high blood pressure or thyroid dysfunction, which can cause arrhythmias. You may also receive a physical exam. The doctor will order one or more heart-monitoring tests to identify and document your arrhythmia.

Arrhythmia testing

There are many types of heart rhythm disorders and many types of tests available to diagnose them. Common diagnostic tests for arrhythmias include:

Electrocardiogram (ECG)

This test is the most basic and generally takes place in your doctor’s office, where a healthcare professional places electrodes on your wrists, ankles and chest for a few minutes to record your heart’s electrical activity. The test does not hurt. The timing and duration of the electrical phases of your heartbeat are recorded. The doctor studies the three waves that appear on the ECG. Each wave represents a different part of the heartbeat and tells the doctor about your heart and its rhythm. This test shows a snapshot of your heart’s electrical activity.


This ultrasound test records sound waves in your heart using a microphone-like attachment. When administering this test and evaluating the results, your doctor can look at your heart in motion. The test can provide a wealth of helpful information, including the size and shape of your heart, its pumping capacity, and the location and extent of any tissue damage.

Holter monitor

This device is a small portable electrocardiogram (ECG) that you wear on your chest or in a pocket to automatically record your heart’s activity. It records your heart rhythm as you go about your daily activities for 24 hours up to 7 days, and provides your doctor with information about changes in your heart rhythm over that period of time.

Event recorder

Like a holter monitor, this is another small, portable electrocardiogram (ECG) that you wear to monitor your heart’s rhythm. When you feel symptoms, you push a button and the device records your heart’s electrical activity. It is often used with patients who have infrequent symptoms.

All your queries. Answered.

Is it very common?

  • By the year 2020, 2.6 million Indians are predicted to die due to coronary heart disease which constitutes 54.1 % of all cardiovascular deaths.
  • Nearly half of these deaths are likely to occur in young and middle-aged individuals (30-69 years).
  • Heart disease has reached epidemic proportions with over 30 million patients and 200,000 surgeries being performed.

What is the cause of serious CVD disorders?

One of the key reasons is the late diagnosis of cardiovascular issues.

What are the symptoms?

In most cases, there may be no symptoms. In some cases, symptoms may include a fluttering sensation in the chest, chest pain, fainting, dizziness or shortness of breath.

What is the treatment?

If needed, treatment includes anti-arrhythmic drugs, medical procedures, implantable devices, surgery.

What is a biosensor?

A wearable biosensor is a battery operated high-tech device. It monitors every beat of your heart for number of days prescribed by your doctor.

Why does my doctor want this test?

Heart Monitoring may be done for the following reasons:

  • Investigation of palpitations, arrhythmias and (or) any heart conditions during the continuous monitoring period.
  • Investigation of dizziness and fainting after a heart attack.
  • To monitor the function of your pacemaker or defibrillator
  • To assess how well medications are controlling your symptoms of a heart rhythm disorder (or) when starting a new heart medicine.

Is this test safe?

The test is painless and non-invasive. There are no risks or dangers. The skin on your chest may, on rare occasions, become irritated when the electrodes and tape are removed. The irritation is caused by the conductive gel on the electrodes reacting with the skin and is perfectly normal

How is the monitoring process achieved?

Allow about 15 minutes to have the biosensor hooked to your chest after which you can continue with your daily routine. After the end of monitoring, it will take another 15 minutes to remove the monitor from your chest. The device will be fitted by a trained clinical technician. Electrodes will be pasted onto your chest. Your skin will be given a mild scrub with paper and wiped with alcohol to facilitate sticking. Men may need to have their hair shaved.

What should I do during the monitoring?

You should go about your routine activities in a normal manner. Cardiac Rhythm will provide you with a diary to complete. You should make an entry every time you feel chest pain, dizziness, breathlessness, palpitations, flutter or any discomfort. You may record what symptoms occurred when and what you were doing at the time.

Is there anything that I should during the monitoring period?

  • During the monitoring period you should not shower, bathe or swim and avoid activities that may get the device wet.
  • Do not use body powder or talcum powder in the chest area.
  • Do not remove the biosensor from the electrodes while the monitoring is in progress. Also, avoid keeping your mobile in your shirt pocket.
  • Do not remove the wires. If a lead wire comes unclipped from an electrode just snap it back on and record this in the pocket diary.
  • Do not drop the biosensor on any hard surface.
  • Do not operate high voltage switches.
  • Do not try to tamper/open the biosensor (or) connect any micro USB to the biosensor.
  • Please stay away from welding, X-Rays and CT machines.

When do I remove the biosensor?

Our technicians will call you and check your availability to visit your home and remove the biosensor from your chest. Alternatively, you may also call our toll-free number and inform the customer support staff to collect the biosensor from you. 

What if I misplace biosensor or if the same gets damaged?

You are liable for the safety of the biosensor. It is your responsibility to return the biosensor in the same condition as it was fixed by our technician. However, in the rare event of the biosensor getting damaged or misplaced, a sum of Rs.1,50,000/- (Rupees One Lakh Fifty Thousand only) is payable by you to “Cardiac Rhythm” towards biosensor recovery costs.

How to use the heart monitor?

  • After your consultation with the doctor, the technical assistant will strap the heart monitor to your chest. You need to wear it uninterrupted for the time period your doctor advises you. On some occasions, you will be asked to wear it for more than one day, up to seven days.
  • You can perform your daily activities like exercise and driving while wearing the heart monitor but you should avoid swimming/showering or any activity that involves direct contact with water while wearing the sensor. While showering, remove the sensor from the electrode/patch and store it in a dry area.
  • During the monitoring period, if you feel any discomfort, you can push the middle button on the bio-sensor thereby recording your symptoms in the monitor with a time code.
  • After the end of your monitoring period, you may visit your doctor’s office. They will assist you in removing the patch and transfer the data for analysis.

Patient's Testimonial


I’ve used a different heart monitor before that was so bulky and frustrating that I couldn’t complete my doctor’s request to wear it for three days. “I’m so thankful that this time I was given the “Cardiac Rhythm” patch monitor, which was both comfortable and easy to wear. Many times I forgot I even had it on me.

Ashwin Kumar


My house is few miles away from my physicians office and it was so convenient for me. A staff of Cardiac Rhythm visited my home spot on time for the hookup and removal of the biosensor, which saved me two visits to my physicians office and the wait.

Rajesh Moorthy


Comfortable and convenient all through seven (7) days on my body. I got an intimation from the Cardiac Rhythm customer care center stating that I was undergoing an arrhythmia and my family immediately transferred me to the hospital’s emergency where my cardiologist was already waiting for me there. I’m back home. Thank you for the close coordination and support.
