Elevating beat

Introduction Lifting-like pulsation refers to a slow, powerful pulsation of the heart, which can lift the tip of the finger and continue until the second heart sound begins. At the same time, the apical beat range also increases, which is the body disease of left ventricular hypertrophy. The systolic pulsation of the lower left sternal border is a reliable indication of right ventricular hypertrophy.

Cause

(1) Changes in apical beat strength and range are affected by physiological and pathological factors.

Increased apex beats - agitation, strenuous exercise, high fever, severe anemia, hyperthyroidism, left ventricular hypertrophy compensation period.

Decreased apex beats - decreased myocardial contractility, pericardial effusion, constrictive pericarditis, emphysema, pneumothorax, and large crab pleural effusion.

(2) Precordial pulsation

The second rib systolic pulsation of the right sternal border was seen in the aortic arch aneurysm and ascending aorta.

The second intercostal systolic pulsation on the left sternal border is seen in pulmonary artery dilatation, pulmonary hypertension, normal youth physical activity, or emotional agitation.

The third and fourth intercostals of the left sternal border were seen in the right ventricular hypertrophy.

The bicep beating is seen in right ventricular hypertrophy and abdominal aortic pulsation (abdominal aortic aneurysm).

General mitral stenosis, regurgitation, aortic stenosis, regurgitation can be typical of the apical area of the lifting pulsation. Also seen in valvular heart disease, hypertrophic obstructive cardiomyopathy, aortic regurgitation, rheumatic aortic stenosis, congenital aortic stenosis, left ventricular hypertrophy.

Differential diagnosis

Differential diagnosis of lifted beats:

1, apical area lifted pulsation - left ventricular hypertrophy.

2, pre-cardiac lift-pulsation - ventricular septal defect.

3, sternal left lower margin systolic lift-up pulsation - right ventricular hypertrophy.

General mitral stenosis, regurgitation, aortic stenosis, regurgitation can be typical of the apical area of the lifting pulsation. Also seen in valvular heart disease, hypertrophic obstructive cardiomyopathy, aortic regurgitation, rheumatic aortic stenosis, congenital aortic stenosis, left ventricular hypertrophy.
