Is left atrial rhythm a disease?

summary

Left atrial rhythms (LAR) was first proposed by Mirowski in 1963 as a regular rhythm with normal heart rate and ectopic rhythm located in the left atrium. It is a rare arrhythmia in clinic. Let's share my experience with you.

Is left atrial rhythm a disease?

Left atrial rhythm mostly occurs on the basis of organic heart disease, such as congenital heart disease (atrial septal defect, ventricular septal defect, patent ductus arteriosus, etc.), rheumatic heart disease, hypertensive heart disease, coronary heart disease, myocardial infarction, pulmonary heart disease, hepatitis, schizophrenia, and some healthy people.

The ectopic pacemaker of left atrial rhythm can be located in the anterior wall, posterior wall, upper or lower part of the left atrium. Due to the different location, the atrial depolarization vector is also different, but the general activation direction is from left to right, so pv6 is always inverted.

When the right atrium is overloaded, it can cause P I inversion, which is easily mistaken for left atrium rhythm. But lead I is not horizontal, but its negative side inclines downward, so when the right atrial load increases. The atrial electrical axis deviates to the right, but not necessarily more than 90 ° It can be projected on the negative side of the axis of lead I to make p I inverted, but the direction of P wave in leads II, III and AVF is normal, and pv5-v6 should be upright.

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.
