Electrical alternans is an electrocardiographic phenomenon of alternation of QRS complex amplitude or axis between beats and a possible wandering base-line. It can be seen in cardiac tamponade and severe pericardial effusion and is thought to be related to changes in the ventricular electrical axis due to fluid in the pericardium, as the heart essentially wobbles in the fluid filled ...
An automatic tachycardia is a cardiac arrhythmia which involves an area of the heart generating an abnormally fast rhythm, sometimes also called enhanced automaticity.These tachycardias, or fast heart rhythms, differ from reentrant tachycardias (AVRT and AVNRT) in which there is an abnormal electrical pathway which gives rise to the pathology.
"Life in the Fast Lane" is a song written by Joe Walsh, Glenn Frey and Don Henley, and recorded by American rock band Eagles for the band's fifth studio album Hotel California (1976). It was the third single released from this album, and peaked at No. 11 on the Billboard Hot 100 .
Cardioversion is a medical procedure by which an abnormally fast heart rate (tachycardia) or other cardiac arrhythmia is converted to a normal rhythm using electricity or drugs. Synchronized electrical cardioversion uses a therapeutic dose of electric current to the heart at a specific moment in the cardiac cycle , restoring the activity of the ...
Many modern ICDs use a combination of various methods to determine if a fast rhythm is normal, supraventricular tachycardia, ventricular tachycardia, or ventricular fibrillation. Rate discrimination evaluates the rate of the lower chambers of the heart (the ventricles ) and compares it to the rate in the upper chambers of the heart (the atria ).
Sinus tachycardia is a normal response to physical exercise or other stress, when the heart rate increases to meet the body's higher demand for energy and oxygen, but sinus tachycardia can also be caused by a health problem. [4] An elite athlete's heart recorded during a maximum effort workout maintaining over 180 bpm for 10 minutes.
Residents see a new life in the fast lane. Melissa Gomez. February 8, 2024 at 6:00 AM. Construction of California's high-speed rail line is evident in cities across the San Joaquin Valley. Here ...
But ventricular tachycardia’s different than, say, a fast heart rate from exercising, which is called as “sinus tachycardia”. Normally, the electrical signals that generates each heart beat starts in the right atrium, at the sinus node, also known as the sinoatrial node or the SA node, if the rate goes over 100 bpm and originates in the ...
