Estimation of Prognosis Using HRV
The association of heart rate variability (HRV) and prognosis, both for all-cause and cardiovascular (CV) mortality, has been studied using ECG at rest, with exercise and in the ambulatory setting. A meta-analysis by Hillebrand and colleagues found that, using both resting and ambulatory ECG monitoring, lower HRV is associated with a 32–45% increased risk of…

Considerable evidence supports the importance that the autonomic nervous system (ANS) has regarding cardiovascular health and prognosis.1 Specific variables derived from heart rate (HR) and heart rate variability (HRV) at rest and with exercise help assess the status of the ANS. Interest has also peaked on the use of HRV to assess the quality of an exercise programme. Among the athletic…

Arrhythmogenic right ventricular dysplasia/cardiomyopathy (ARVD/C) is a rare heritable cardiomyopathy characterised by fibro-fatty replacement of the myocardium, which predisposes patients to frequent lifethreatening ventricular arrhythmias and slowly progressive ventricular dysfunction.1,2 Structural involvement of the right ventricle (RV) generally predominates,3,4 although left dominant forms…

Monomorphic ventricular arrhythmias (MMVA) are not uncommon in athletes,1,2 yet their presence appropriately raises concern among practitioners for possible increased risk of sudden cardiac death (SCD) during sports activity and competition. While all MMVA detected in athletes warrant further evaluation,1 a majority of MMVA in this population are likely to be benign. In some instances of so…

Sudden unexplained death syndrome (SUDS)1 is rare in the young but when it occurs it is devastating for family and friends, and affects whole communities. That it can affect fit, athletic individuals and may be related to competitive sports only adds to the sense of incomprehension and injustice felt by wider society. In comparison with the older population, where sudden death is more common and…

Although atrial fibrillation (AF) is considered the most common arrhythmia in clinical practice, its prevalence is relatively low in the young and middle-aged, ranging from 0.5 % in men below 40 years to 1 % by 60 years.1,2 Regular exercise is proposed as a powerful tool for the primary and secondary prevention of cardiovascular disease, reducing most of the risk factors that predispose to AF,…
