“…Interestingly, Chow et al., described a 66‐year‐old man with an intermittent LBBB triggered by laughter in the absence of heart rate changes. In that case, the patient was admitted because of syncope immediately after a bout of laughter and coughing.…”

Episodic (transient/ intermittent) left bundle branch block (LBBB) has been associated with different conditions such as bradycardia, tachycardia, anesthesia, acute pulmonary embolism, changes in intrathoracic pressure, chest trauma, cardiac interventional procedures, mad honey poisoning, and in other clinical settings. Of note, exclusion of an acute coronary syndrome in the setting of episodic LBBB is of great importance. Moreover, episodic LBBB is sometimes symptomatic and may be associated with left ventricular systolic and/or diastolic dysfunction or conduction disturbances leading to syncope. This review article provides a comprehensive overview of the conditions associated with episodic LBBB and discusses the clinical impact of this phenomenon.

“…It has been reported with exercise, tachycardia, ischemic and hypertensive heart disease, hyperkalemia, drugs, anesthesia, pulmonary embolism, chest trauma, and cardiac interventional procedures [ 8 - 12 ]. Apart from transient LBBB, RBBB, bifascicular block, and advanced AV block have also been reported [ 13 - 15 ].…”

Hyperkalemia is one of the most common electrolyte abnormalities seen in clinical practice and the most common life-threatening electrolyte abnormality seen in the emergency department. It is most often due to impaired renal potassium excretion due to acute on chronic kidney disease or the use of drugs that inhibit the renin-angiotensin-aldosterone axis. The most common clinical presentation is muscle weakness and cardiac conduction abnormalities. In the Emergency Department, ECG can come in handy as the first diagnosis of hyperkalemia before labs are drawn and reported. Early recognition of electrocardiographic (ECG) changes can prompt early correction and reduce mortality. We hereby, present a case of transient left bundle branch block in the setting of hyperkalemia secondary to statin-induced rhabdomyolysis.

“…He subsequently had triple vessel disease on coronary angiogram. Successful percutaneous intervention to the left circumflex artery was done after which the LBBB was not induced by laughing, raising the likelihood that the mechanism of LBBB was ischemia-driven [10]. To the best of our knowledge, there is no prior documented case of control of LBBB with coughing.…”

A Curious Case of Intermittent Left Bundle Branch Block Associated with Cough

A handful of cases of voluntary control of left bundle branch block (LBBB) have been described in the literature. We report the case of a middle-aged man who was found to have LBBB on baseline electrocardiogram (ECG) which disappeared on coughing and then reappeared with the same maneuver. Subsequent myocardial perfusion scan showed reduced count in the anteroseptal region likely attributed to LBBB. It is possible that the intermittent conduction changes may be due to the alteration in the vagal tone associated with cough as reflected in the change in the PR interval on the ECG.
