The trifascicular rhythm of the heart is a gallop rhythm (heartbeat in a gallop), in which only three tones are heard: the first tone (S1) and two extra tones (S2 and S4).
A three-membered heart rhythm is observed with incomplete blockade of the right bundle branch, in which the excitation impulse passes through the myocardium only through the right bundle branch. In this case, the first sound (S1), which corresponds to contraction of the atria, is heard clearly, and extratones (S2, S4), which correspond to contraction of the ventricles, may not be heard or weakened.
A three-membered heart rhythm can be a sign of various diseases of the cardiovascular system, such as myocardial infarction, arrhythmias, right bundle branch block, etc. To establish a diagnosis, it is necessary to conduct additional studies, such as electrocardiography, echocardiography, etc.
It is important to note that heart rate is not the only indicator of the state of the cardiovascular system. Therefore, for an accurate diagnosis, it is necessary to take into account all research results and the clinical picture as a whole.
Heart rhythm Trinomial
Heart rhythm is the vibration that occurs in the heart as it pumps blood through the blood vessels. Heart rhythm can be of different types and have different characteristics. One of the most common heart rhythms is the gallop rhythm - or the Triple rhythm. This rhythm contains only one frequency of sound - extratone, which makes it a particularly interesting object for study.
Threefold heart rhythms - theory
A three-part rhythmic sound occurs when the heart does not work properly. Such rhythms are associated with impaired blood circulation through the veins and pulmonary veins. These veins originate from the heart and are carried through the lungs to the lungs. If the heart is not working well, blood flow through these pathways may slow down or stop altogether. This causes the sound wave to propagate through the pulmonary trachea and propagate to the diaphragm, where it is perceived as a paroxysmal tone. This sound has a low frequency, which gives it the character of an echo - paroxysms and three-part rhythms usually occur together. As the paroxysm progresses into cardiogenia, sometimes accompanied by supraventricular tachycardia, the heart rate increases and the three-part sound becomes louder. Eventually the heart rate reaches approximately 300 beats per minute.
