What does rSr pattern in V1 mean?

The rSr’ pattern can be considered a normal variant due to delay in the activation of the basal part of the right ventricle (RV). It has been reported that an rSr’ pattern is a common finding in the general population.

What does rSr mean in ECG?

Definition. An electrocardiographic finding in which there are two R waves, which are two deflections above the baseline resulting from a single ventricular depolarization. The first upward deflection in the complex is the R wave.

What causes rSr in V1?

We often face this finding in asymptomatic and otherwise healthy individuals and the causes may vary from benign nonpathological variants to severe or life-threatening heart diseases, such as Brugada syndrome or arrhythmogenic right ventricular dysplasia.

How serious is right ventricular conduction delay?

Conclusions— Prolonged QRS duration in a standard 12-lead ECG is associated with increased mortality in a general population, with intraventricular conduction delay being most strongly associated with an increased risk of arrhythmic death.

How is right ventricular hypertrophy diagnosed?

RVH is diagnosed on ECG in the presence of a R/S ratio of greater than 1 in lead V1 in the absence of other causes, or if the R wave in lead V1 is greater than 7 millimeters tall. The strain pattern occurs when the right ventricular wall is quite thick, and the pressure is high, as well.

What are the precordial leads?

The precordial leads, or V leads, represent the heart’s orientation on a transverse plane, providing a three- dimensional view (see Precordial Views). They are placed anatom ically over areas of the left ventricle. 1 Like the augmented leads, the precordial leads are unipolar with an electrically neutral center.

What is the treatment for right ventricular conduction delay?

Cardiac resynchronization therapy (CRT) is an electrical treatment of heart failure with reduced ejection fraction and wide QRS. It aims to correct the electrical dyssynchrony present in 30\% to 50\% of patients in this population.

Can right bundle branch block cause death?

You may not need any treatment at all for right bundle branch block. People without any symptoms do, however, need careful evaluation at the time of diagnosis. In people with known or suspected heart disease, right bundle branch block is associated with a greater risk of death, especially after a heart attack.

How serious is a right bundle branch block?

A block in the right bundle branch can occur in people who otherwise seem normal. If it happens with a heart attack, it can be a sign of serious heart muscle damage. A block in the left bundle branch is usually a sign of heart disease. Bundle branch blocks usually do not cause symptoms.

Is right ventricular hypertrophy serious?

Right ventricular hypertrophy doesn’t always cause symptoms, which means it often isn’t discovered until its later stages. If left untreated, it can lead to some serious complications, including heart failure.
