Arrhythmia refers to all kinds of symptoms that are caused by abnormalities in the cardiac electrical conduction system. It includes irregular heartbeat, rapid heartbeat, as well as slow heartbeat. Severe arrhythmia will cause dizziness, syncope, and even cardiac arrest and sudden death. Research shows that half of the deaths from cardiovascular diseases are caused by sudden cardiac arrest from arrhythmia. While arrhythmia is often overlooked, the related diseases produce a massive economic burden. In most cases, arrhythmia can be controlled or treated through accurate diagnosis, pharmacotherapy, defibrillator implant, catheter ablation, and other surgeries.
Atrial fibrillation is the most common type of arrhythmia. Compared to non-patients, atrial fibrillation patients have a much higher rate of death, heart failure, and stroke. Atrial fibrillation has a prevalence rate of 0.5% – 2%. There are approximately 100 million atrial fibrillation patients around the world, with about 10 million patients in China, 5.1 million patients in the U.S., and 4.5 million patients in Europe. However, due to an insufficient diagnosis rate, this is still only the tip of the iceberg. Since the occurrence of atrial fibrillation increases with age, population aging is expected to drastically increase the global number of atrial fibrillation patients by at least 2.5 times by year 2050. Most atrial fibrillations are paroxysmal and even asymptomatic, which result in the currently serious insufficient diagnosis rate.
