 Hello friends, this is Dr. Bhupen Singh, consultant cardiologist, Manipal Hospital, Gajibath. Today, I will talk about abnormal heart beating. Normal heart rate is between 6200 beats per minute. If your heart rate is less than 60 beats per minute, it is called as low heart rate or bradycardia. If it is more than 100 beats per minute, it is called as high heart rate or tachycardia. In normal resting condition, your heart rate remains on the lower side and during working or exercising, this heart rate becomes higher side. If even in the resting condition, if your heart rate is on higher side, you need to consult a doctor. Normally, heart rate is regular but if it becomes irregular, this medical condition is known as atrial fibrillation. To diagnose these medical conditions, we need 24 hour or longer duration ECG recording. We call this as Holter monitoring. Atrial fibrillation is a serious medical condition in which clot formation can occur inside the heart which can embolize to brain and ultimately this can lead to CVA or paralysis. This condition is more common in elderly, those who are hypertensive, diabetics and those who have associated coronary artery disease or thyroid conditions. If you are experiencing any palpitation, sudden in non-sat, if you are experiencing faintness, extreme weakness, fatigue, I suggest you to consult your doctor. Thank you.
