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.

Even if you have had norovirus before, you can still be infected every year, because there are many different types of the bug, owing to the rapid mutation rate seen in RNA viruses like norovirus.
Also, left ventricular hypertrophy may be absent in children under thirteen years of age. This undermines the results of pre-adolescents' echocardiograms. [ 15 ] Researchers, however, have studied asymptomatic carriers of an HCM-causing mutation through the use of CMR and have been able to identify crypts in the interventricular septal tissue ...
No, that doesn’t make a team that has won three Super Bowls in six years a fluky fraud either. Even last Sunday’s field-goal block wasn’t just a product of good luck. Kansas City identified ...
