I am 66 years old and have periodically had increased PVC's causing symptom an d both bradycardia and tachycardia. For the past 4 months I have had consistent symptoms of lightheadedness, dizzyness, chest pressure and shortness of breath periodically and dailey. I have had 2 48 hour holters and a 28 day non event monitor. The monitors reveal ventricular bigeniny, ventricular trigeminy ventricular couplets pvc's, pac's, sinus bradycardia as low as 36, and sinus tachycardia as high as 208. I am scheduled to see a rythme specialist cardiologist, and 3 months ago they started verapamil and I have been on clonidine for 4 years for hypertension. Where do you think this may be going and are there specific questions I should be asking?
