Use of a Smartwatch for Assessment of the QT Interval in Outpatients with Coronavirus Disease 2019.

The coronavirus disease 2019 (COVID-19) pandemic has necessitated rapid implementation of innovative strategies to manage patients remotely to help reduce the risk of community and nosocomial transmission. This case demonstrates the use of an Apple Watch (Apple, Cupertino, CA, USA) to monitor for arrhythmias and QT prolongation in a patient with COVID-19 during home isolation.

Bradyarrhythmias in patients with COVID-19: Marker of poor prognosis?

Background: Despite descriptions of various cardiovascular manifestations in patients with coronavirus disease 2019 (COVID-19), there is a paucity of reports of new onset bradyarrhythmias, and the clinical implications of these events are unknown.

Methods: Seven patients presented with or developed severe bradyarrhythmias requiring pacing support during the course of their COVID-19 illness over a 6-week period of peak COVID-19 incidence. A retrospective review of their presentations and clinical course was performed.

Cardiac Implantable Electronic Device Implantation: Intraoperative, Acute, and Remote Complications.

Implantation of cardiac implantable electronic devices (CIEDs), including pacemakers, implantable cardioverter-defibrillators, and biventricular pacemakers/cardioverter-defibrillators, is becoming increasingly common with new implants now exceeding 1.5 million per year globally. As a result, health care providers in all disciplines are caring for an increasing number of patients with CIEDs.

Transvenous dual site left ventricular pacing to lower elevated pacing thresholds.

Dual site left ventricular pacing through two left ventricular pacing leads, located in discrete vessels, significantly lowered pacing thresholds from 6 V at 1 ms and 4.25 V at 0.5 ms through the leads individually, to 0.
