Cough-induced Nonsustained Ventricular Tachycardia

Intravenous Lidocaine for the Prevention of Cough: Systematic Review and Meta-analysis of Randomized Controlled Trials

“…On emergence from anesthesia, cough may protect against aspiration. However, cough can also result in perioperative morbidity, including tachyarrhythmia, arterial hypertension, cardiovascular collapse, and airway complications, [1][2][3][4][5][6][7][8][9] and it may increase intracranial, intraabdominal, and intraocular pressure. 10 An effective technique for preventing cough would be desirable in many situations where patients are at a particular risk.…”

Cough as a Cause and Consequence of Heart Dysfunction - Current State of Art

“…Cough-triggered ventricular tachycardia: Although the cough has been recommended as a tool for reversal of life-threatening ventricular tachyarrhythmias, some reports pointed towards an opposite situation, i.e. triggered by cough attacks ventricular tachycardia (VT) (Reisin et al 1994). The example can be the coughinduced VT in a patient with a left ventricular assist device described by Ruckdeschel et al (2016).…”

“…It has been shown that significant intrathoracic and intraabdominal pressure swings associated with a forceful coughing may affect a maintenance of blood flow during unstable cardiac rhythm, e.g. ventricular fibrillation, asystole or even bradycardia and hypotension that may occur after intracoronary injections of contrast medium (Wei et al 1980, Reisin et al 1994, Lo Mauro and Aliverti 2018). Furthermore, it was estimated that cough may generate approximately 1 to 25 J of kinetic energy, which is sufficient enough to even convert the arrhythmia by its effect on cardiac depolarization (Reisin et al 1994, Girsky andCirley 2006).…”
