“…The initiation of VT was associated with a typical catecholamine surge seen on exercise in the setting of the presence of arrhythmogenic substrate characteristic of these patients. 21,22) Therefore, as exercise may increase heart rate in a pregnant woman with a diagnosis of ARVC, it is better to recommend to avoid exercise.…”

Arrhythmogenic Right Ventricular Cardiomyopathy in Pregnancy

SummaryArrhythmogenic right ventricular cardiomyopathy (ARVC) is predominantly a genetically determined heart muscle disorder that is characterized by fibro-fatty replacement of the right ventricular (RV) myocardium.1) The clinical spectrum of ARVC may represent from asymptomatic premature ventricular complexes to ventricular tachycardia (VT) and sudden cardiac death (SCD). It is a well-known leading cause of SCD in young adults. 2,3)There is no general consensus on the management of ARVC in pregnancy, and the preferred mode of delivery is uncertain. Herein, we report a case of ARVC diagnosed at 20 weeks of gestation following a sustained VT and treated with an implantable cardiac defibrillator (ICD). We also reviewed the current knowledge and approach to ARVC in pregnancy since the literature on this condition is based on case reports. (Int Heart J 2014; 55: 372-376)

“…Strenuous exercise, sport and acute mental stress are major triggering factors (23-100%) of SCD in patients with RVC [324][325][326][327] . Patients with RVC should therefore be strongly discouraged from practicing competitive sports.…”

“…It has been shown that physical exercise is a precipitating factor for lethal ventricular arrhythmias in patients with ARVC. 5 Corrado et al 27 reported that sudden cardiac death occurred among young ARVC patients, and Leclercq et al 28 documented VT on a 24-hour Holter ECG after an autonomic imbalance of increasing sympathetic tone in ARVC patients. Furthermore, it has been reported that adrenergic stimulation, an isoproterenol infusion mimicking the catecholamine effect, induced VT with ARVC.…”

Background— Late potentials (LP) detected with signal-averaged ECGs are known to be useful in identifying patients at risk of Brugada syndrome (BS) and arrhythmogenic right ventricular cardiomyopathy (ARVC). Because the pathophysiology is clearly different between these disorders, we clarified the LP characteristics of these disorders. Methods and Results— This study included 15 BS and 12 ARVC patients and 20 healthy controls. All BS patients had characteristic ECG changes and symptomatic episodes. All ARVC patients had findings that were consistent with recent criteria. Three LP parameters (filtered QRS duration, root mean square voltage of the terminal 40 ms of the filtered QRS complex, and duration of low-amplitude signals [<40 µV] in the terminal, filtered QRS complex) were continuously measured for 24 hours using a novel Holter-based signal-averaged ECG system. The incidences of LP determination in BS (80%) and ARVC (91%) patients were higher than in healthy controls (5%; P <0.0001 in both) but did not differ between BS and ARVC patients. In BS patients, the dynamic changes of all LP parameters were observed, and they were pronounced at nighttime. On the contrary, these findings were not observed in ARVC patients. When the SD values of the 3 LP parameters (filtered QRS duration, root mean square voltage of the terminal 40 ms of the filtered QRS complex, and duration of low-amplitude signals [<40 µV] in the terminal, filtered QRS complex) over 24 hours were compared for the 2 patient groups, those values in BS patients were significantly greater than those in ARVC patients ( P <0.0001 in all). Conclusions— LP characteristics detected by the Holter-based signal-averaged ECG system over 24 hours differ between BS and ARVC patients. Dynamic daily variations of LPs were seen only in BS patients. This may imply that mechanisms of lethal ventricular arrhythmia in BS may be more correlated with autonomic abnormality than that of ARVC.
