For patients with more than 1,000 PVCs per day, the risk of developing left ventricular systolic dysfunction after 5 years follow-up is low. Frequent PVCs may increase the risk of developing cardiomyopathy, which can greatly impair heart function. A PVC burden greater than 10% is the minimal threshold for development of PVC-induced cardiomyopathy.
Recently published data suggest that the use of selective beta blockers, such as atenolol, bisoprolol, or metoprolol, is associated with very high treatment failure rates. [ 25 ] Flecainide is a class 1c antiarrhythmic drug that is recommended for those with CPVT who experience abnormal heart rhythms despite taking a beta blocker. [ 2 ]
Bigeminy is a cardiac arrhythmia in which there is a single ectopic beat, or irregular heartbeat, following each regular heartbeat.Most often this is due to ectopic beats occurring so frequently that there is one after each sinus beat, or normal heartbeat.
PVCs that occur at intervals of 2 normal beats to 1 PVC, or 1 normal beat to 2 PVCs, are termed "PVCs in trigeminy" [13] Groups of three premature ventricular beats are called triplets and are considered a brief run of non-sustained ventricular tachycardia (NSVT); if the grouping lasts for more than 30 seconds, it is considered sustained ...
Frequent multifocal PVCs (both singly and in pairs) and left atrial enlargement. (BOTTOM): Same patient about 5 months later status-post orthotopic heart transplant. Dilated cardiomyopathy on CXR Dilated cardiomyopathy on CT. Generalized enlargement of the heart is seen upon normal chest X-ray.

Treatment antiarrythmic agents , diuretics , catheter ablation , pacemaker [ 1 ] Tachycardia-induced cardiomyopathy (TIC) is a disease where prolonged tachycardia (a fast heart rate) or arrhythmia (an irregular heart rhythm) causes an impairment of the myocardium (heart muscle), which can result in heart failure .
