Researchers at the University of California, Irvine, have developed a polymeric biohybrid cardiac device that harnesses the power of light to electrically and mechanically control living heart tissue ...
S1 is the first heart sound that doctors can hear using a stethoscope. The vibrations that occur when the mitral and tricuspid valves in the heart close produce the S1 sound. There are two common ...
In a new research report, a team of scientists led by Johns Hopkins Medicine say people with severe obesity and a common type ...
Palpitations due to premature beats, either ventricular contractions (PVCs) or atrial contractions (PACs), can be extremely vexing even when we know they are benign. For many individuals, these ...
One promising strategy to remuscularize the injured heart is the direct cardiac reprogramming of heart fibroblast cells into cardiomyocytes. Researchers have identified TBX20 as the key missing ...
Excessive calcium in the blood, known as hypercalcemia, can disrupt the heart’s electrical system, potentially leading to an irregular heartbeat or arrhythmia. Hypercalcemia is more likely to cause a ...
