Not a lot with that little information. the various wave forms on an ECG are given letters p q r s t . The p wave is the little up lift before the big wiggle and shows the atrium contracting. This is missing with AF. The qrs complex is the big wiggle so the q wave is the first part of the stroke. Without more info about it there is nothing to draw from but you do need one. lol 😁

I don’t have one! But still here ☺️

Depends all on context.

As BobD states part of the ECG morphology.

Can be pathological ie post myocardial infarction, but can also be totally normal.

Would suggest a discussion with your clinician.

i think you ask the question with a bit of misconception, that's all Jackyg. You seem to have got the impression that what was 'noticed' in your ECG was something irregular or abnormal. In fact the q wave is there on everyone's ECG.

The "Q" wave, if it were missing on one of the leads apparently, can also show something called "left bundle branch block", which I have. I was told it is not all that uncommon and almost certainly of no consequence.

Another aspect is the interval between the Q wave and the S wave, which, if longer than a certain time, can show a "wide QRS", again, which I often also have. This is another common finding with the bundle branch blocks, I gather,

I would ask your doctor to interpret it but, from what I have been told and read, it's nothing whatsoever for you to worry about.

Interested to read your response Ppiman, as following a recent ECG, I was advised by GP that it showed a wide Q Wave. This has resulted in me being referred to a cardiologist. Any advice from anyone regarding questions to ask would be much appreciated - Alan

Hi - I think your doctor might well have meant a "wide QRS". These can be a normal finding, I gather, one that comes and goes, often with exercise, or can sometimes be a sign of a "bundle branch block" (left or right).

These aren't physical blockages but altered electrical pathways. The electrical signals of the heart start in its own natural pacemaker called the sino-atrial (SA) node which is in the top left chamber and causes the top of the heart to squeeze blood down into the bottom chambers, through one way valves. Once in the ventricles, they pump the blood to the body and the lungs. Owing to the block, the signal to the lower chambers has to travel via a different and longer route, so the blood pumps out slightly later than otherwise would happen. Usually this is symptomless and harmless, I was told, but can cause symptoms in some people, as I’ve discovered from internet searches.

Many thanks Steve for your useful and prompt response. - Alan

I was wondering, do you have any symptoms, Alan?
