The researchers have studied the alcohol drinkers during Munich Octoberfest which was held in Germany. This Octoberfest is the world’s largest beer festival that lasts for 16 to 18 days. It begins in mid-September and lasts till the first week of October.

For the purpose of a study, the researchers analyzed the alcohol drinkers during this beer fest. The Department of Medicine at University Hospital Munich have studied the link between alcohol consumption and the risk of abnormal heart rhythms.

The research study was published in the European Heart Journal on Wednesday in which the link between alcohol consumption and cardiac arrhythmias was studied. Many past studies have claimed that heavy alcohol consumption causes “Holiday Heart Syndrome”. Even the individuals who did not have any history of heart disorders have developed abnormal and cardiac arrhythmias.

The conducted study

The Octoberfest was the first study that has proved this association by experimenting on 3,028 voluntary participants that attended this fest in 2015. All the participants were provided with smartphone-based ECG and their alcohol concentration in breath was determined using breath analyzer. The ECG patterns were studied to check the cardiac arrhythmias, sinus arrhythmia, sinus tachycardia, premature atrial/ventricular complexes, and atrial fibrillation/flutter. In all these participants, abnormal heart rhythms were observed in 30.5 percent individuals. Every 1-gram of alcohol per 1-kilogram blood increases the risk of abnormal heart rhythms by 75%.

The findings of the study are important because abnormal heart rhythms can lead to severe discomfort and in the worst case may cause heart failure and stroke.

In some countries like Germany. The researchers also studied the impacts of habitual and chronic alcohol consumption among 4131 participants in a study called KORA S4.

Although the researchers have been successful in determining the link between alcohol and abnormal heart rhythms, the medical experts cannot trace out how this can help in clinical trials.
