The experience of being ill can be like waking up in a foreign country. Life, as you formerly knew it, is put on hold while you travel through this other world as unknown as it is unexpected. When I see patients in the hospital or in my office who are suddenly, surprisingly ill, what they really want to know is “What is wrong with me?” They want a road map that will help them manage their new surroundings. The ability to give this unnerving and unfamiliar place a name, to know it—on some level—restores a measure of control, independent of whether that diagnosis comes attached to a cure. Because, even today, a diagnosis is frequently all a good doctor has to offer.

When you see absent P-waves, you must check whether the rhythm is regular or irregular based on the QRS complex:-

- Irregular and normal QRS: most likely to be atrial fibrillation.

- Regular: if the QRS < 120 ms (narrow), then it's likely to be paroxysmal SVT.
If the QRS > 120 ms (wide) then it's probably VT.

JUST TO BE CLEAR: This is an oversimplification with a lot of buts and ifs.
For example, some paroxysmal SVTs can present with wide QRS if they're associated with pre-existing LBBB.

In AF, the P-wave is either absent or it's replaced by rapid, variable, irregular and low-amplitude oscillating fibrillatory waves.

Also, the diagnosis of VT is defined as: tachycardia (>100-120 bpm), and the rhythm originates below the bundle of His (in the ventricles, therefore it is a ventricular rhythm).

Usually, you can tell if the rhythm is sinus or ventricular by observing the P-wave & the QRS complex. If QRS is wide and P-waves are absent or dissociated from the QRS (not every P-wave is followed by QRS) then it's most likely to be ventricular rhythm.

A wide QRS happens in VT because the rhythm originates in the ventricles and this makes the depolarization of the ventricles slower and takes a longer time (indicated by wide QRS > 120 ms)
