Consequently, the direction of atrial activation may be altered, which can be seen as an abnormal P-wave axis on the electrocardiogram (ECG). The appearance of the P-wave depends on the site of origin of the ectopic rhythm. The P-wave can be decreased in amplitude, or it can be ...
Normal blood levels of potassium are critical for maintaining normal heart electrical rhythm. Both low blood potassium levels (hypokalemia) and high blood potassium levels (hyperkalemia) can lead to abnormal heart rhythms. The aim of the work presented is to study the effect of potassium ...
Cardiac amyloidosis is where abnormal proteins, called amyloid, build up in the heart tissue, making the heart stiff and less able to pump blood. If left untreated, it is likely to be fatal within four to six years. Importance of Early Detection Senior author Dr Luis Lopes, from the U...
Fig. 3: Abnormal high levels of FA in the hippocampus and cerebellum in the mouse model of hindlimb unloading which simulates weightlessness by using tail suspension to unload the hind limbs. Schematic overview of an in-vivo animal imaging system with a NaFA probe was used to image brain FA...
COVID-19 infection may negatively affect the cardiovascular system and result in abnormal ECG readings. Long-term COVID-19 patients frequently exhibit sinus tachycardia [46]. Studies have revealed that the occurrence of any arrhythmia in patients with COVID-19 is associated with higher mortality as...
An increasing number of people in the Asia-Pacific region are living with AF. In China alone, up to eight million people suffer from AF, an abnormal heart rhythm and a major risk factor for stroke. AF causes the heart to beat irregularly, allowing blood to pool and create clots, which ...
My condition is actually somewhat common, or more common than people think. I have an arrhythmia—an abnormal heart rhythm caused by electrical impulses that have gone haywire. There are many different kinds arrhythmia. Some cause the heart to beat too quickly; others, too slowly or too erratic...
seizures, which sometimes happen instead of a blackout when the brain is starved of oxygen heart palpitations, when the heart is beating in a fast or unpredictable way Long QT syndrome is usually caused by a faulty gene inherited from a parent. The abnormal gene affects the ...
One option is medications, including anticoagulant drugs that "thin" the blood, reducing the risk of an abnormal clot that can form in the heart and migrate to the brain (the definition of a stroke). A statement from Fetterman's physician suggests that he was not taking those drugs. Being...
It has long been known that resveratrol has cardio-protective effects and seems to prevent some rhythm disorders of the heart, lowers blood pressure and reduces enlargement of the heart. "We have had a tremendous amount of success with resveratrol and have been at the leading edge of resveratrol...
