Supraventricular tachycardia (SVT) is an umbrella term for fast heart rhythms arising from the upper part of the heart. [2] This is in contrast to the other group of fast heart rhythms – ventricular tachycardia , which start within the lower chambers of the heart . [ 2 ]
SVT in the lower extremities can lead to a dangerous complication in which the clot travels to the lungs, called pulmonary embolism (PE). [3] This is because lower limb SVTs can migrate from superficial veins into deeper veins. [3] In a French population, the percent of people with SVTs that also suffered from PEs was 4.7%. [3]
Paroxysmal supraventricular tachycardia (PSVT) is a type of supraventricular tachycardia, named for its intermittent episodes of abrupt onset and termination. [3] [6] Often people have no symptoms. [1] Otherwise symptoms may include palpitations, feeling lightheaded, sweating, shortness of breath, and chest pain. [2] The cause is not known. [3]
An episode of SVT may present with palpitations, dizziness, shortness of breath, or losing consciousness (fainting). The electrocardiogram (ECG) would appear as a narrow-complex SVT. Between episodes of tachycardia the affected person is likely to be asymptomatic; however, the ECG would demonstrate the classic delta wave in Wolff–Parkinson ...
The causes listed are relatively immediate medical causes, but the ultimate cause of death might be described differently. For example, tobacco smoking often causes lung disease or cancer, and alcohol use disorder can cause liver failure or a motor vehicle accident.
The survey also found that 18% of people erroneously named cancer as the leading cause of death, while 16% said they didn’t know, and 49% correctly identified heart disease.
Multifocal (or multiform) atrial tachycardia (MAT) is an abnormal heart rhythm, [2] specifically a type of supraventricular tachycardia, that is particularly common in older people and is associated with exacerbations of chronic obstructive pulmonary disease (COPD).
“Though we have made strides in the past 20 years, cardiovascular disease remains the leading cause of death in the United States and our community,” said Augusta Health’s Chief Physician ...
