The role of continuous monitoring in a 24/7 telecardiology consultation service—a feasibility study

Remote surveillance view of central monitor display of arrhythmic events in a patient with an implanted cardioverter defibrillator.

Technical aspects of remote access from the telecardiologist's laptop computer to the hospital. The VPN solution provided a secure connection to the hospital intranet based on smart card authentication. A fixed Internet connection using an ADSL was used as the physical access technology.

An alarm showing ventricular tachycardia with attempt for conversion to sinus rhythm by antitachycardia pacing by the implanted cardioverter defibrillator device.

Alarm showing nonsustained ventricular tachycardia.

Trend curve showing rapid ventricular rate in atrial fibrillation in a patient postbypass surgery.

Alarm for loss of capture in a patient with temporary pacing through epicardial leads postheart surgery.

ST-deviation trends in channels V2 and V5 from the derived 12-lead EASI ECG system indicating episodes of myocardial ischemia.

Motion artifact simulating ventricular tachycardia revealed by second channel.
