ABSTRACT
Although a 12-lead ECG recorded while the patient is asymptomatic might indicate the probable nature of the arrhythmia (for instance, the finding of a short PR interval makes atrioventricular re-entry tachycardia a likely diagnosis, whereas a long QT interval makes ventricular tachycardia (VT) more likely), there is no substitute for obtaining an ECG recording during an episode of palpitations. There are five ways in which this can be achieved:
● 24-h ambulatory ECG recording ● event recorder ● ECG ‘on demand’ ● bedside monitoring/telemetry (inpatient) ● implantable loop recorder.
