what does rsr on ecg mean

by Ms. Jaunita Reilly DDS Published 3 years ago Updated 2 years ago

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. The S is the first downward deflection.

Full Answer

What does RSR on ECG mean?

What is a P wave:

  • upright I, aVF and V3 - V6 leads
  • normal duration of less than or equal to 0.11 seconds
  • polarity is positive in leads I, II, aVF and V4 - V6; diphasic in leads V1 and V3; negative in aVR
  • shape is generally smooth, not notched or peaked

What is RSR on EKG?

RSR'; RSR' by EKG Finding Definition An electrocardiographic finding in which there are two R waves, which are two deflections above the baseline resulting from a single ventricular depolarization.

What is right ventricular conduction delay?

Heart Conduction Disorders

  • Rhythm versus conduction. Your heart rhythm is the way your heart beats. ...
  • Bundle branch block. Normally, electrical impulses travel down the right and left branches of the ventricles at the same speed.
  • Heart block. ...
  • Long QT Syndrome (LQTS) Long QT Syndrome, also called LQTS, is a disorder of the heart’s electrical system, like other arrhythmias.

What is the normal range of ECG?

ST segment:

  • isoelectric, slanting upwards to the T wave in the normal ECG
  • can be slightly elevated (up to 2.0 mm in some precordial leads)
  • never normally depressed greater than 0.5 mm in any lead

What causes rSr?

An RSR' pattern in V1-3 may also be caused by Brugada syndrome — an ECG pattern associated with malignant ventricular arrhythmias.

What does rSr in V1 mean on ECG?

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 is a 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 does right ventricular conduction delay mean?

In general, “conduction delay” refers to a slight widening of the QRS complex, especially in the right precordial leads (leads V1, V2, and V3); it is sometimes also called incomplete right bundle branch block.

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 Brugada syndrome?

Brugada syndrome is a rare but serious condition that affects the way electrical signals pass through the heart. It can cause the heart to beat dangerously fast. These unusually fast heartbeats – known as an arrhythmia – can sometimes be life threatening.

What causes rSr in V1?

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.

How serious is a right bundle branch block?

How serious is a right bundle branch block? If you have no symptoms and no heart disease, a right bundle branch block is not serious. But if you've already had heart failure or a heart attack along with right bundle branch block, it puts you at a higher risk of death.

What is the treatment for a right bundle branch block?

If you have bundle branch block with low heart-pumping function, you may need cardiac resynchronization therapy (biventricular pacing). This treatment is similar to having a pacemaker implanted. But you'll have a third wire connected to the left side of your heart so the device can keep both sides in proper rhythm.

Is right ventricular conduction delay common?

Delayed intraventricular conduction is a common clinical abnormality detected on the electrocardiogram (ECG). This topic will review the basic aspects of this problem [1,2]. More complete discussions of left and right bundle branch block are presented elsewhere.

Is intraventricular conduction delay serious?

Intraventricular conduction delay usually has no prognostic significance in patients without underlying heart disease but may progress to complete heart block or ventricular arrhythmia with worse prognosis in underlying heart disease.

What is the treatment for intraventricular 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. Dyssynchrony results in widening of the QRS complex on the electrocardiogram (ECG).

What does rsr' in v1 or v2 mean on an ecg?

Likely normal: Rsr', pronounced 'r s r-prime' can be a normal finding in leads v1 and v2. This pattern is often found in young healthy people. An rsr' with widening of the qrs and characteristic findings in other leads is due to a right bundle branch block.

What does rsr stand for if in v1 or v2 on ecg?

Right Bundle: It's ekg notation for the shape of the waveform, and it means there's either block or delay in one of the heart's 3 "wires" (they're not really wires) that conduct the electrical impulse to the lower chambers. It does not, generally, mean increased risk of death or problems unless other circumstances are present.

First, The QRS Complex

What Is An RSR Prime (Rsr’)?

  • Now that we know the parts of the QRS complex, an rSR’ is simple. It is an R-wave, followed by an S-wave, followed by another R-wave. In other words, an upward deflection, followed by a downward deflection, followed by another upward deflection. Voila! That’s it. When an ECG reader mentions it, though, he/she is referring to an rSR’ in leads V1 and...

What Is The Significance of An rSr’ in Leads V1 and/or V2?

  • As mentioned above, most of the time an ECG reader mentions an rSR’ pattern on the ECG, the QRS complex is narrow or only mildly prolonged. A majority of the time this finding is a benign finding from abnormally high lead placement of V1 and V2, a normal variant seen due to normal depolarization of the intraventricular septum, or an incomplete right bundle branch block. Additi…

rSr’ in V1 Or V2 with A Wide QRS Complex

  • An rSR’ in V1 or V2 in a widened QRS complex is abnormal. This may be due to a right bundle branch block (RBBB), preexcitation or Wolff Parkinson White(WPW), or a ventricular beat.

What Do I Do with A Reading of An Rsr’?

  • As you may have guessed by now, most of the time, and rSR’ is a benign finding. It is often from lead misplacement, is a normal variant, or may indicate a slight right ventricular conduction delay. Clinically this finding is insignificant and does not affect the patient’s prognosis. Remember that this finding is really only mentioned with regard to leads V1 and V2. When I read an ECG, I comm…
