The Woodpecker phenomenon

The Woodpecker phenomenon

Among patients with various cardiac pathologies, 5-15% are identified by a voice emanating from the upper lobe of the lungs and called the Woodpecker phenomenon (in Greek Orthos - the correct orientation, if the contraction of the right side of the heart is combined with a high short sound at the Botkin point, in the second key, it is possible assume that this is really Dux Cockerelli). In this article we will discuss what this phenomenon is, what diseases can cause it, and how they are treated.

Sinus tachycardia: What does the doctor say?

This term describes a heart rhythm disorder where the heart beats faster than normal.

This is not an independent disease, but a symptom of many diseases. Sinus tachycardia can affect various organs

**The Woodpecker Phenomenon**

The phenomenon, named after the woodpecker, is a sudden change in the intervals between tones (I and II). Knowing the duration of these intervals, the physiological status of the myocardium can be determined. The main function of rhythm (R-R interval) is cardiac output. The A-A interval corresponds to the diastolic function of the myocardium. The first tone depends on the functional reserves of the myocardium, and also characterizes the venous inflow to the heart.

First of all, the phenomenon of bifurcation of the first tone is detected in fatal combined pathology of the myocardium (myocardial dystrophy or arrhythmias). This phenomenon may be unexpressed or mildly expressed in AMI, MI or systemic cardiovascular diseases (coarctation of the aorta, cardiosclerosis or myocardiosclerosis). There are three types of split tones: I, II and double. However, in severe heart failure, with the exception of cases with the presence of SA and TA, the second tone is predominant, and we are dealing with a bifurcation of the second tone.

If, with pathology of the main valve (BA), the ascending part of the circuit disappears during normal operation of the VA, then we are talking about bifurcation of the first tone. If, instead of the ascending part of the main stage, “jaggedness” appears, indicating cardiac arrhythmia, then we are talking about a bifurcated II tone. When amplified
