Recurrent Syncope Episodes and Exercise Intolerance in Hypertrophic Cardiomyopathy Combined with Atrioventricular Conduction Disturbance
A 30-year-old female patient with known hypertrophic cardiomyopathy (HCMP) was admitted for recurrent syncope episodes. Electrocardiogram (ECG) showed 2 : 1 atrioventricular (AV) block. Stress echocardiography with bicycle showed high grade AV block at high stage of the exercise associated with exercise intolerance and dyspnea. Twenty-four hour ECG monitoring also revealed high grade AV block a...
متن کاملAbrupt aggravation of atrioventricular block and syncope in hypertrophic cardiomyopathy.
A 10 year old girl with hypertrophic cardiomyopathy (HCM) developed high grade atrioventricular (A-V) block unexpectedly, which instantly led to syncope; she required a permanent pacemaker. High grade A-V block, a rare complication of HCM, relates closely to syncope or sudden death in this disease and if progressive the use of cardiac pacing should be considered without delay.
متن کاملSyncope in hypertrophic cardiomyopathy.
A patient with hypertrophic cardiomyopathy, syncope, and frequent ventricular tachycardia was monitored during a syncopal episode. An unrecordable blood pressure and the loss of a left ventricular outflow tract murmur without evidence of arrhythmia suggested a primary haemodynamic mechanism such as reduction in left ventricular volume.
متن کاملApical hypertrophic cardiomyopathy presenting as recurrent unexplained syncope.
Apical hypertrophic cardiomyopathy (AHC) is a rare variant of hypertrophic cardiomyopathy. Since its description by Sakamoto in 1976 in Japanese patients, our understanding of this entity has evolved. Although cardiac magnetic resonance imaging has emerged as the gold standard for diagnosing AHC, clinical attention must be drawn to the unique electrocardiographic features that provide the initi...
متن کاملModification of atrioventricular conduction as adjunct therapy for pacemaker-treated patients with hypertrophic obstructive cardiomyopathy.
AIMS Atrioventricular synchronous pacing offers symptomatic relief for patients with drug-refractory hypertrophic obstructive cardiomyopathy. Successful treatment requires complete right ventricular apical pre-excitation. Enhanced atrioventricular conduction renders this difficult in some patients. The aim of this study was to evaluate whether selective prolongation of atrioventricular conducti...
