A 70-year-old woman was admitted to the intensive coronary care unit with suspected myocardial infarction. During the follow-up period, the patient twice developed left bundle branch block, which was shown to be related to high serum potassium levels secondary to hyporeninemic hypoaldosteronism and moderate renal failure.

Left ventricular hypertrophy in left bundle branch block
Journal of Electrocardiology, 1984The detection of left ventricular hypertrophy (LVH) in the presence of left bundle branch block (LBBB) remains a difficult clinical problem. Its prevalence and significance have not previously been studied in a group of living patients. M-mode echocardiography was utilized to determine the prevalence of anatomic LVH in 28 patients with LBBB.

Laughter‐Induced Left Bundle Branch Block
Journal of Cardiovascular Electrophysiology, 2012Laughter‐Induced LBBB. We present the case of a patient with ischemic heart disease and intermittent left bundle branch block, reproducibly induced by laughter. Following treatment of ischemia with successful deployment of a drug‐eluting stent, no further episodes of inducible LBBB were seen.

[CME: Left Bundle Branch Block and Painful Left Bundle Branch Block Syndrome].
Praxis, 2020CME: Left Bundle Branch Block and Painful Left Bundle Branch Block Syndrome Abstract. Left bundle branch block (LBBB) is the electrocardiographic correlate of a pathologic transmission of the electrical signals in the myocardium which can lead to a dyssynchronous left ventricular activation and thus to an inefficient contraction of the ventricles.

Postoperative Episodic Left Bundle Branch Block
A & A Case Reports, 2014Transient left bundle branch block (LBBB) associated with physical exertion has been described in patients with and without coronary artery disease. A 64-year-old woman with no history of coronary artery disease underwent Nissen fundoplication under general anesthesia. Preoperatively, an exercise-tolerance test revealed LBBB, without ischemic symptoms.

Of 27 patients with left bundle-branch block following acute myocardial infarction, five died. Left bundle-branch block was present on admission in 26 patients, and subsequently appeared in one. Fourteen of 16 patients who did not have a temporary pacemaker placed prophylactically survived the acute myocardial infarction.
