One of the more frequent dilemmas in ECG interpretation is the differential diagnosis of an rSr pattern in leads V 1-V 2. In general conduction delay refers to a slight widening of the QRS complex especially in the right precordial leads leads V1 V2 and V3.

One of the more frequent dilemmas in ECG interpretation is the differential diagnosis of an rSr pattern in leads V1 -V2.
. The isolated presence of RSr pattern in lead V1 with QRS 120 ms isolated pattern of partial RBBB can be considered a normal variant due to delay in the activation of the right ventricle RV located at proximal or peripheral aspect of the right bundle. Normal Sinus rhythm Possible Left Atrial enlargement RSR or QR pattern in V1 suggests right ventricular conduction delay Borderline ECG Anything to worry about. Should I be concerned.
Compared with other ECG signs Qr in V 1 is the strongest predictor of right ventricular dysfunction and it is highly associated with troponin leakage and myocardial shear stress. 1 The history should focus on causes of pulmonary hypertension and RV enlargement such as previously diagnosed valvular conditions mitral stenosis pulmonary stenosis congenital abnormalities atrial septal defect chronic. What does all that mean.
6 mm or S 2mm or rSR with R 10 mm. This is when the electrical pathway to the right ventricle is slower than the pathway to the left venricle typically. RSR in V1 or V2 with a Wide QRS Complex.
Right bundle branch block can exist in the absence of any other significant heart disease and may not do much harm by. More than 012 seconds. 6 mm or S 2mm or rSR with R 10 mm.
Right ventricular conduction delay means late blood pumping from the right ventricle of the heart. RSR pattern in V1-3 M-shaped QRS complex Wide slurred S wave in lateral leads I aVL V5-6 RBBB. The differential diagnosis of an rSr pattern in leads V1-V2 on electrocardiogram is a frequently encountered entity in clinical cardiology.
RSR pattern in V1 suggests right bundle branch block RBBB. Widened slurred S wave in V6. 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.
Shown below is an EKG with an RSR pattern in lead V1 an RSr pattern in lead V2 and wide QRS complexes in leads V1 and V2 depicting a right bundle branch block. It is sometimes also called incomplete right bundle branch block. Any one of the following in lead V1.
The causes might vary from benign and nonpathological to severe and life. ECG Diagnostic criteria. Right Bundle Branch Block.
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. 16 patients 20 of cases had different patterns of rsR type. RSR in V1 or V2 probable normal variant Borderline r wave progression anterior leads Female 38 52 100 lbs Been having heart flutters and lightheaded.
In RBBB the interventricular septum wall separating left and right chambers is activated normally and the electrical impulse travel rapidly down the left bundle branch to activate the right ventricle. R in V1 S in V5 or V6 10 mm. An rSr pattern in the right precordial leads is a relatively common electrocardiographic finding that has been described in up to 7 of patients without apparent heart disease.
Interpretation on ekg says sinus rhythm Low Voltage in precordial leads - RSRV1-non diagnostic - Horizontal axis for age. A Verified Doctor answered A US doctor answered Learn more. What do I do with a reading of an rSR.
This pattern is often found in young healthy people. This finding often presents itself in asymptomatic and healthy individuals. RSR pattern in V1 with appropriate discordant T wave changes.
The right bundle branch taking signals to the right ventricle can often have a conduction delay and the manifestation on ECG is called right bundle branch block RBBB. Rsr pronounced r s r-prime can be a normal finding in leads v1 and v2. But because the right bundle branch is blocked the impulse must then must cross the interventricular septum to.
R in V5 or V6 5 mm. The most common cause of this is just being a normal variant in other words there is nothing wrong with the heart. Other chest lead criteria.
Ecg results1100 sinus rhythm2420 rsr qr in lead v1v2 consistent with right ventricular conduction delay9130 borderline ecg. Hypertrophy andor dilatation will result in delayed activation of some regions of the right ventricle resulting in the classic rSr pattern. 142 QT316 QTcH372 QRSD96 P-QRS-T47-1041.
An rSR in V1 or V2 in a widened QRS complex is abnormal. As you may have guessed by now most of the time and rSR is a benign finding. RSR or QR pattern in V1 suggests right ventricular conduction delay Possible Left atrial enlargement Left ventricular hypertrophy with repolarization abnormality Nonspecific T wave abnormality.
S in V5 or V6 7 mm. RS ratio 1 and negative T wave. Qr in V 1 and the presence of negative T waves in V 2 or V 3 also predict a complicated hospital course and therefore are useful for risk stratification in pulmonary embolism.
4 If the QRS is wide the presence of an R in leads V 1 V 2 usually is in the context of a complete right bundle branch block RBBB but other causes have been described. RS ratio in V5 or V6 1. A Practical Approach to the Investigation of an rSr Pattern in Leads V1-V2.
In 30 patients 375 of cases in lead V1 there was an rS or RS pattern. Appropriate discordance with ST depression andor. Read Responses 4 Follow.
It is characterized as a long QRS complex Ie. This may be due to a right bundle branch block RBBB preexcitation or Wolff Parkinson White WPW or a ventricular beat. Normal Sinus rhythm Possible Left Atrial enlargement RSR or QR pattern in V1 suggests right ventricular conduction delay Borderline ECG Anything to worry about.
It has a characteristic pattern on the ECG with an rSR pattern in the lead V1. 21 patients 26 of cases had a. An rsr with widening of the qrs and characteristic findings in other leads is due to a right bundle branch block.
