Heart Rhythm

Hearts should have normal rhythm to their beats, but when these beats are out of synch, it causes inefficient pumping of blood. Irregular heart arrhythmias occur when the electrical signals that coordinate the heart's beats do not work properly. This can cause beats that are too fast (tachycardia), or too slow (bradycardia). Tachycardias include atrial fibrillation (AFib), supraventricular tachycardia, ventricular fibrillation, and ventricular tachycardia (VT). Bradycardias include sick sinus syndrome and conduction block. Electrophysiology arrhythmia treatments include medications, life style changes, and the EP lab interventions of catheter ablation, and implantable pacemakers or defibrillators.

Hypertension patients measured their blood pressure less frequently during the early months of the COVID-19 pandemic, according to new research published in Hypertension. In addition, when those patients did measure their blood pressure, the readings were less healthy than they had been before the pandemic.

A potential risk: New studies highlight the connection between treating COVID-19 with hydroxychloroquine and QTc prolongation

Treating COVID-19 patients with hydroxychloroquine, alone or in combination with azithromycin, is associated with an increased risk of QTc prolongation, according to two new studies published in JAMA Cardiology.
