My dr ran an echo-stress test this morning, but my heart rate would not go over 88.
Yes, sotalol can suppress heart rate.
Accelerated ventricular tachycardias refractory to overdrive pacing in patients on propafenone (the active ingredient contained in Rythmol SR) who had arrhythmias previously responsive to overdrive pacing, have been reported.
Cardiovascular side effects may be serious. Two to four percent of patients have experienced a proarrhythmic effect. Propafenone slows conduction throughout the myocardial conduction system with very little effect on repolarization, resulting in a prolonged PR interval and QRS complex. Cases of bradycardia, sinus pauses and arrest, accelerated reentrant tachycardia, AV block, and ventricular tachycardia, including torsades de pointes, have been reported.
Propafenone has negative inotropic activity.
