I don’t have any symptoms except for 2 instances when I felt a bit dizzy. However, I’ve been diagnosed with sick sinus syndrome and have both bradycardia and tachycardia indicated by a Holter. I have a smart bracelet that vibrates when my heart rate exceeds 100. Some days it vibrates only twice in one day, other days more frequently but goes back down immediately. I will get a pacemaker for the bradycardia and medication for the tachycardia. I’ve been reading emails on the site and I’m quite surprised by people commenting on symptoms post implant. Is this common? My heart rate has always been slow in the 40s and 50s. I’m 72 and very active and have never complained of feeling tired but wondering if I will feel anything when they increase the pace. Could I feel more energetic? Or could it feel like anxiety? Or should I put on the deep relaxation music and learn to live with it?
