Key result

A 56-year-old woman presenting with lethargy and dizziness was diagnosed with complete heart block and a severely prolonged QT interval requiring urgent pacemaker placement.

Key Points

To evaluate a complex 12-lead electrocardiogram in a symptomatic patient presenting with dizziness and lethargy to establish the correct rhythm diagnosis and management strategy.
Clinical and electrophysiological evaluation of a 56-year-old woman presenting with a 2-week history of dizziness and lethargy on thiazide therapy.
Systematic analysis of simultaneously recorded 12-lead electrocardiogram formats, comparing lead-by-lead deflections, rhythm strip continuity, and axis vectors.
The electrocardiogram demonstrated sinus tachycardia at an atrial rate of 102 beats per minute completely dissociated from a ventricular escape rhythm at 42 beats per minute, confirming complete heart block.
The ventricular escape rhythm exhibited a wide QRS duration of almost 120 ms, a QRS axis of minus 30 degrees, and an enormously prolonged QT interval measuring 700 ms.
Apparent absence of QRS complexes in limb lead II was resolved by recognizing that ventricular depolarization was perpendicular to that lead while regular dissociated T-waves remained visible.

Population

A 56-year-old woman with a history of hypertension and stroke presenting with lethargy and dizziness, found to have complete heart block and a prolonged QT interval.

This case highlights the critical need for systematic multi-lead ECG analysis to accurately diagnose complete heart block and prolonged QT interval, which urgently requires pacemaker implantation to prevent fatal arrhythmias.

Implication

Systematic multi-lead ECG review aids diagnosis of complete heart block with QT prolongation; this case report leaves broader applicability open.

Abstract

56-year-old woman with a past history of hypertension and a stroke 2 years ago, currently only on a thiazide, attended a peripheral hospital clinic complaining of lethargy and dizziness for the past 2 weeks. An ECG was done and sent through for an opinion regarding management.
