If you have a slow heart rate and are experiencing symptoms like fainting and tiredness, you should make an appointment with your GP. Exercise and your heart rate It’s estimated that more than 2 million people in the UK experience heart rhythm issues. Most of them will be able to lead normal lives. Fast heart rate (tachycardia) If you are experiencing symptoms or have a fast resting heart rate you should make an appointment with your GP. Symptoms to look out for include:

The arrhythmogenic potential of caffeine is controversially discussed in the literature [ 19]. In a review by Goldfarb et al., 17 cases of acute cardiovascular events related to ED consumption in individuals between 13 and 58 years—15 thereof under 30 years—were identified. The cardiovascular events described varied from atrial and ventricular arrhythmias to QT-prolongation, ST-segment elevations, and cardiac arrest. In five of these cases, acute heavy ED consumption was described, four reported co-ingestions with alcohol or other party drugs, and two were found to have a channelopathy [ 20]. These adverse effects may be associated with the high caffeine content in EDs. Nevertheless, the relevance of these data may be limited by the retrospective data collection and the inhomogeneous study cohorts. Contrary to the results of our prospective study design, the presence of illegal substances, prior chronic caffeine consumption before the ED intake, as well as the comorbidity with other cardiovascular risk factors cannot be excluded in those data and may have potentiated the arrhythmogenic effect of the EDs. An invasive prospective placebo-controlled, randomized, electrophysiological study performed by Lemery et al. found that caffeine, at moderate intake (5 mg/kg), was associated with a significant increase in systolic and diastolic blood pressure but had no significant effect on cardiac conduction and refractoriness. Furthermore, caffeine intake at a moderate level showed no effect on supraventricular tachycardia induction or other forms of tachycardias [ 8]. Vagal maneuvers are techniques that can help lower a person’s heart rate. They target the vagus nerve, which has a key function in the parasympathetic nervous system. Research that experts presented at the European Heart Rhythm Association 2018 Congress showed that a higher breath alcohol concentration was associated with increases in heart rate. Coca-Cola is committed to making a positive difference - to the health of the planet, consumers and the communities it serves. The company is working hard to reduce its impact on the environment in everything it does - growing more while using less in areas such as energy and water use, waste reduction and recycling - and by encouraging people to think more about the positive impact they can have on their local environment.This study was a randomized, double-blind, placebo-controlled, crossover clinical trial conducted between April and October 2021 at our institution. On two consecutive days, the participants received either a commercially available caffeinated ED or a placebo drink without the conventional ingredients found in an ED (e.g., caffeine, taurine). They were randomly assigned to the two study groups (Group I: day 1: ED, day 2: placebo; Group II: day 1: placebo, day 2: ED). You can find your normal resting heart rate by counting the number of times your heart beats in a minute. Sitting still for 5 - 10 minutes before counting makes sure your heart is in its resting state. Knowing your normal heart rate when living with your heart condition can help you feel more confident and improve your quality of life. What’s a dangerous heart rate? The bottle is 100% recyclable, so please recycle when you're finished. We use partly recycled and fully recyclable bottles, refuse to air freight and source ethically Energy drinks (ED), marketed for providing mental and physical stimulation, are beverages containing stimulant compounds such as caffeine [ 1]. Though some of their side effects on the cardiovascular system, such as arterial hypertension, are well-known, the acceptance of such drinks remains very high, especially among teenagers.

Previous data suggest that the steepness of the QT–RR relationship depends on HR [ 26]. A decrease in HR leads to higher RR intervals and thus to a flattened QT–RR relationship [ 27]. Hence, the significantly decreased QT–RR relationship shown in this study may be explained by the significantly lower HR observed.

Reimers AK, et al. (2018). Effects of exercise on the resting heart rate: A systemic review and meta-analysis of interventional studies. It is important that a person speaks with a doctor before trying any vagal maneuvers. Getting enough sleep Traumatic experiences, grief, and certain mental health conditions stress the body, which can sometimes make it harder for people to perform everyday activities. In these cases, counseling and therapy may be helpful. Getting outdoors
