Electrocardiographic (ECG) monitoring is routinely used in hospitals for patients with a wide range of cardiac and non-cardiac diagnoses. Besides simple monitoring of heart rate and detection of life-threatening arrhythmias, the goals of ECG monitoring include detection of myocardial ischaemia, diagnosis of complex arrhythmia, and identification of a prolonged QT interval. The ECG remains a cornerstone in diagnosis and management of patients with coronary ischaemia. Over the past decade, there has been an increase in the number and complexity of electrophysiological interventions, including complex ablations, biventricular pacing, and insertion of implantable defibrillators. ECG monitoring in these patients can serve both a protective and diagnostic purpose. They detect life-threatening arrhythmias and double up as in-patient Holter monitors. Unfortunately, there are no randomized controlled trials of in-hospital cardiac monitoring—expert opinions based on clinical experience and published research in the field of electrocardiography form the basis of current guidelines.
