Webb19 nov. 2024 · A heart rate that is very fast or very slow can result in too little blood flowing through the heart. In some cases this can lead to heart failure, or you may collapse. It can be very difficult to detect an arrhythmia in a young child, when the only clue may be a change in behaviour or a problem with feeding.
Webb8 aug. 2024 · This slows impulse formation at the sinus node, slows conduction velocity at the AV node, lengthens the AV node refractory period, and decreases ventricular inotropy. The Valsalva maneuver is performed expiring against a closed glottis, and needs to be held for 10 seconds to 15 seconds. bismuth everyday usesWebbThe slow propagation is due to zig-zag conduction through the myocyte strands as well as gap junction remodeling.
