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.

ICE-guided Watchman procedures linked to safety concerns—is TEE better for LAAO or will things improve?

TEE and ICE are each associated with certain advantages and disadvantages, researchers explained. The new analysis included data from nearly 40,000 patients.

Cardiologists give recycled pacemakers to heart patients in need

When patients with pacemakers die, what happens to the device? Typically, it ends up being discarded and forgotten—they were designed to be single-use devices, after all—but that does not have to be the case.
