Can left atrium enlarge to die slowly?
summary
Left atrial enlargement refers to the enlargement of the heart volume, generally a certain part of the heart, or a general enlargement of the heart. Let's share my experience with you.
Can left atrium enlarge to die slowly?
The P wave of ECG represents the activation of left and right atria. Since the sinoatrial node is located under the intima of right atrium, the activation first spreads to right atrium, and later to left atrium. When the left atrium is enlarged, the conduction of activation to the left atrium is delayed, and the conduction of activation in the left atrium is also delayed, resulting in the broadening of P wave duration and the appearance of "double peak" phenomenon.
The correlation between P-wave voltage and left atrial diameter is 0.69, which is consistent with our result of 0.683. The mechanism may be related to the increase of left atrial pressure. At the same time, patients with mitral stenosis and enlargement of left atrium often have enlargement of right atrium and right ventricle. Enlargement of right atrium leads to increase of P wave voltage and sharp P wave height
Diagnosis: apical pulse shifted to the left and down, palpation showed obvious lifting pulsation, the boundary of percussion heart murmur enlarged to the left and down, ECG showed left axis deviation and left ventricular hypertrophy. Echocardiography can be used for direct diagnosis.
matters needing attention
In daily life, eat more fruits and vegetables, keep optimistic mood, pay attention not to fatigue, pay attention to the recovery of the body, in addition, if there are any symptoms should go to the hospital for examination, and corresponding treatment, these are to actively do.
