Diltiazem: A Reversible Cause of Atrioventricular Block – Until Proven Otherwise
نویسندگان
چکیده
Drugs are considered a common reversible cause of rhythm conduction disorders. Atrio-ventricular (AV) block occurs more commonly following β-blocker or digitalis administration, but calcium channel blockers have also been linked to AV block [1,2] The cornerstone of management in drug-related AV block is to determine whether the AV block is truly reversible upon withdrawal of the culprit drug, hence implantation of a permanent pacemaker can be avoided.

Drug-induced atrioventricular block: prognosis after discontinuation of the culprit drug.
OBJECTIVES The goal of this study was to determine how often atrioventricular (AV) block is really caused by medications. BACKGROUND Beta-blockers, verapamil, and diltiazem are considered a cause of AV block for which pacemaker implantation is not indicated. However, it is not known if such patients can expect a benign course after discontinuation of the culprit medication. METHODS Consecut...
متن کاملDiltiazem-induced Transient Complete Atrioventricular Block in an Elderly Patient with Acute on Chronic Renal Failure
Diltiazem is a calcium channel blocker commonly used in the treatment of various cardiovascular disorders such as hypertension, angina and supraventricular tachycardias. Metabolism occurs mainly in the liver, but a small percentage of unchanged drug and metabolites are excreted in the urine. Toxicity from this medication usually presents in the form of dysrrhytmias and heart block. Hence, we pr...
متن کاملTermination of paroxysmal supraventricular tachycardia with a single oral dose of diltiazem and propranolol.
The efficacy of a single oral dose combination of 120 mg diltiazem and 160 mg propranolol in terminating paroxysmal supraventricular tachycardia (PSVT) was evaluated in 15 patients. All 15 patients underwent electrical induction of PSVT that lasted longer than 15 min, and all underwent randomized crossover placebo and diltiazem and propranolol studies on 2 consecutive days. On each day PSVT was...
متن کاملSequential Coronary Spasm in Prinzmetal’s Angina Presenting as Syncope
Prinzmetal or variant angina, described for the first time half a century ago,1 is a rare cause of myocardial ischemia. The pathophysiological basis of this condition is reversible coronary spasm that usually appears at rest and, therefore, presentation as multivessel coronary spasm is rare. We describe a 56-year-old woman recently diagnosed with hypertension. Chlorthalidone therapy was started...
