Summary

Current guidelines advocate that ARVC patients, typically young and active individuals with a significant history of competitive endurance sports, cease endurance training in favour of activities with low cardiac burden such as bowling and golf. Empirically, it is often suggested that heart rate during exercise should not exceed 100-120 bpm in these patients, but these guidelines are arbitrary and not scientifically based. In practice, it is estimated that up to 50% of patients do not comply with these recommendations . Adequate quantification of the arrhythmogenic burden, defined as premature ventricular beats in proportion to all heart beats in each period of time, and cardiac load (defined as stroke volume for volume load and systolic blood pressure for pressure load) experienced by ARVC patients when performing different types of physical exercise would be a first step towards designing a safe and effective intervention so that these patients can profit from an active life style. This study therefore aims to quantify and describe the arrhythmogenic burden and cardiac load experienced by patients with ARVC while performing different physical exercise over a range of intensities - all strictly within the range currently recommended by different cardiological societies.

Detailed description

In this study, ARVC patients with different genotypes will perform a series of different physical activities, including treadmill walking, cycling at different intensities, biceps curls and loaded squats while undergoing extensive cardiovascular monitoring.
