What does rSr on ECG mean?
What does rSr on ECG 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 causes rSr ECG?
An RSR’ pattern in V1-3 may also be caused by Brugada syndrome — an ECG pattern associated with malignant ventricular arrhythmias.
What does rSr pattern in V1 mean?
The rSr pattern in leads V1-V2 can be found in benign or sever life-threatening heart diseases, including the Brugada syndrome or arrhythmogenic right ventricular dysplasia.
What are inferior leads in ECG?
Lead II, aVF and III are called inferior limb leads, because they primarily observe the inferior wall of the left ventricle (Figure 18, coordinate system in upper panel). Lead aVL, I and –aVR are called lateral limb leads, because they primarily observe the lateral wall of the left ventricle.
Why does Sinus bradycardia occur?
Key points about sinus bradycardia Sinus bradycardia is a kind of slow heartbeat. It happens when the sinoatrial node fires less than 60 times per minute. In some cases, sinus bradycardia is normal, but other times it can mean an underlying problem.
What is RSR complex?
The abnormal RSR’ complex arises from a terminal conduction delay (dissimilar to either RBBB or LBBB using the vectorcardiogram) of left ventricular (LV) depolarization within impaired tissue surrounding the infarct scar.
What is sinus arrhythmia of the heart?
Sinus arrhythmia is a variation of normal sinus rhythm that characteristically presents with an irregular rate in which the change in the R-R interval is greater than 0.12 seconds. Additionally, the P waves are typically monoform and in a pattern consistent with atrial activation originating from the sinus node.
What is ST elevation in inferior leads?
An inferior wall MI — also known as IWMI, or inferior MI, or inferior ST segment elevation MI, or inferior STEMI — occurs when inferior myocardial tissue supplied by the right coronary artery, or RCA, is injured due to thrombosis of that vessel.
