Dejerine's reflex

In physiology, the Dejerine reflex, among others, is defined as the only protective reflex during shock. And now there are a lot of patients with some kind of omission in ECG analysis. We are talking about the possibility of false widening of the QRS complex. And most importantly, all these problems need to be considered without any assessment of the specific person who gave the electrocardiogram. The QRS complex during the Dejerine reflex changes extremely towards enlargement of the amplitude of the waves and the duration of all intervals decreases. In response to this, the body's defense mechanism arises, which is expressed in hyperventilation of the lungs and redness of the skin, and even sometimes in temperature and heartbeat. In a healthy person, the QRS complex changes very moderately - almost only in height (across the frame).

When performing a reflex, to distinguish it from a painful or secretory one, it is necessary to consider the heart rate every 3 intervals after the moment of maximum impact on the finger. Increase in amplitude up to 1 mm in the left pectorals from
