On an ecg, what does a "persistent s-wave ( v5-v6 )" mean?

On an ecg, what does a "persistent s-wave ( v5-v6 )" mean?

Not much: on the ECG, the first downward deflection that follows the dominant upward deflection is called an "S" wave and is part of the depolarization complex (called a "QRS complex"). Classically, the S wave is tiny or absent in V5-6. When the S wave is deep, the term "clockwise rotation" is used. (your heart is rotated in your chest) It doesn't connote any pathology. Not to worry. ...Read more

Electrocardiogram (Definition)

Electrocardiogram (ecg, ekg) is a print-out of the electrical forces detected by electrodes on the chest wall, as electricity travels through the heart with each heart beat. The electrodes are placed in different positions, and each position "sees" the electrical activity of the heart from its own vantage point. Abnormalities in signal detected at chest surface ...Read more

Ecg: Persistent S wave in the lateral precordium doesn't have any particular evil important, it is often a normal finding. Occasionally it can be seen with pathologic conditions but there are generally other associated findings. ...Read more

Can you tell me if on an ecg, what does a "persistent s-wave ( v5-v6 )" and mean?

Depends: A small S wave in these leads is usually normal. A prominent S-wave may be seen in patients with right sided overload conditions, such as pulmonary disease. A large S wave in V1 and lead I when the QRS is wide is seen in right bundle branch block (RBBB). In rare cases, a person with dextrocardia may be diagnosed by ECG with one feature being a persistent s-wave in V5-V6. Review with your doctor. ...Read more

I had a Notched S wave in lead V2 on my ECG is this something serious? It wasn't there 2 years ago.

Possibly: Need to interpret the ECG in its entirety. May indicate a delay in the electrical conduction in the lower chambers of the heart. Sometimes stress testing is done to evaluate for coronary artery blockage as an origin for ecg abnormalities. ...Read more

Hi Dr ,My ECG is showing R/S INVERSION AREA BETWEEN V1 AND V2 .PROBABLY ABNORMAL ECG. WHAT DOES THIS MEANS?

R > S in V1-2.: I assume u mean R taller than S is deep in V1-2. Could be normal, could indicate some true abnormalities. At your age more likely normal, BUT, rather than list all the abnormalities here, u should see your doc for full evaluation and discussion. Good luck. ...Read more
