Hello, Welcome to Healthcare Magic. I have read your question fully and understand your concerns. Normally heartbeat should be between 60-100 beats/minute. But there are plenty of people who have their heartbeat slightly lower than the above given range. It can be either perfectly normal or could be because of disturbances of the electrical conduction system of the heart. Some people like athletes and other people who are very fit and exercise a lot have a slow heartbeat due to vagal tone. This is entirely normal. As a person grows old, his heart beat slows down too. This could be normal for him. Some people are on medicines called beta blockers (like propranolol, atenolol) and digoxin etc., these drugs cause a slower heart beat too. Hypothyroidism results in slow heartbeat. Heart problems can cause slow heart rate too. As long as your heartbeat is above 50 beats/minute and as long as you do not have any symptoms like chest pain, breathlessness, dizziness, missed heartbeats, palpitations (pounding heartbeat), tiredness, fainting episodes etc., I would not worry too much. Slow heart beat may be normal for you. If your heart beat is less than 50 and irrespective of whether you have symptoms or not, I would advise you to see your doctor for routine review (so as to rule out any significant causative factors). You would be asked to get an ECG or a holter tape (continuous ECG for 24hours) and may be an ECHO (heart scan). You are asked to get blood tests to rule out a thyroid problem, and if there is any medication causing the slow heartbeat, that would be changed. If patient is asymptomatic, he may not be treated. Symptomatic patients are fitted with a pacemaker that will increase the heart rate. I hope this answer has helped you. Thank you Regards Dr Sunita Sayammagaru
