Elevated resting heart rate is a risk factor for sudden death in middle-aged mendoi:10.1054/ebcm.2001.0389PaoloPalatiniSDOSEvidence Based Cardiovascular Medicine
We found a non-linear association between resting heart rate and SCD; the value of ≥ 90 beats per/min was accompanied by 72% increased risk. In the meta-analysis including five prospective studies, the researchers found a linear association between heart rate with SCD, and every 10 numb...
That said, people who have genetic predispositions to arrhythmia (an abnormal heart rate) may be more at risk for sudden cardiac arrest. However, athletes who are training for long races should undergo a physician’s evaluation to assess for any symptoms or high-risk features in their family ...
The intrinsic HR generated by the sinoatrial node (SA node) in the absence of any neural or hormonal influence is about 100 to 120 beats per minute (BPM). However, in healthy individual, resting HR would never be that high. The normal resting adult human heart rate ranges from 70–75 bp...
Sudden cardiac death (SCD) is a sudden, unexpected death that is caused by the loss of heart function. While SCD affects many patients suffering from coronary artery diseases (CAD) and heart failure (HF), a considerable number of SCD events occur in asymptomatic individuals. Certain risk factor...
Investigations in animal models of PNE have demonstrated that nicotine significantly diminishes resting ventilatory activity and responses to hypoxia in neonatal rats (St-John and Leiter, 1999). PNE increases the parasympathetic control of heart rate in baboon fetuses. These changes in heart ...
In epidemiologic studies, a high resting heart rate is associated with decreased survival and increased SCD [1]. In 2005, a meta-analysis of randomized controlled trials found resting heart rate to be reduced by 2.5 beats per minute, if >69 beats per minute at baseline [32]. The results ...
After a recovery period, heart rate was evaluated with a standard ECG. A high inverse linear correlation between heart rate and the SE-strength index (R2 = 0.9207) was observed, suggesting that the heart rate reduction was increased according with SE severity (Figure 1B). 2.2. ECG Changes...
