Despite significant advancements in prevention and treatment, sudden cardiac death remains a major cause of mortality, accounting for approximately 50% of all cardiovascular disease-related deaths. Unfortunately, outcomes for those who experience sudden cardiac arrest remain poor, with few individuals surviving.
Speaking about this, Cardiac Electrophysiologist Dr. Deep Chandh Raja, Cardiologist & Clinical Lead of Cardiac Electrophysiology, Kauvery Hospital, Mylapore, Chennai stated that it’s important to know that our heartbeat is controlled by electrical impulses. Any changes in these impulses can cause irregular heartbeats, also known as arrhythmia. In some cases, the heart can stop beating altogether, leading to cardiac arrest. Ventricular Tachycardia or Ventricular Fibrillation are conditions where the heartbeat becomes rapid and disorganized, significantly reducing blood flow to the brain and causing loss of
Taking preventive measures like regular screenings, identifying underlying risk factors, and promptly treating any issues can significantly reduce the risk of sudden cardiac arrest (SCA) and sudden cardiac death (SCD). Several factors can increase the likelihood of SCA and SCD, like undetected diabetes mellitus, high levels of bad cholesterol, bad lifestyle, coronary heart disease, a family or personal history of abnormal heart rhythms, or congenital birth defects, he added.
