Patient's Query

Hello doctor,

I am 68 years old with a weight of 167 pounds and a height of 5 feet 9 inches. I had a bypass surgery seven years ago. I used to walk 45 minutes daily. I feel completely fit and fine. A week ago, I felt that my heart rhythm was irregular. After going through a Holter test, I found that my heart rate increases and slows down with a pause of 1.8 seconds. My minimal heart rate is 50 beats per minute and the maximum is 144 BPM. My average heart rate is 89 beats per minute. Is there anything serious? More details about the presenting complaint include I rarely get a headache with no other symptoms. I am currently taking Razel Gold once a day. In the past, I have been on Concor 5 mg once a day and Razel Gold once a day. I have gone through TMT three to four months ago with a normal outcome. The doctor also did an echocardiogram and everything seemed normal. Please help.


Welcome to icliniq.com.

I have gone through the first page of the Holter report (attachment removed to protect patient identity). You seem to have supraventricular tachycardia episodes likely atrial fibrillation or flutter. You have sinus pauses and sinus arrest suggesting sinus node dysfunction. You will need treatment for supraventricular tachycardia episodes like rate control medication and anticoagulation if it is atrial fibrillation. Your sinus node dysfunction currently does not require any treatment. Consult a cardiologist for starting treatment.

Same symptoms don't mean you have the same problem. Consult a doctor now!
