What Does This Heart Electrical Activity Indicate?
Question: my qrs is 72 my qt interval 432 im tiedal te time
Brief Answer:
Normal QRS duration 0.06 to 0.10 sec and QT is ≤ 0.40 sec.
Detailed Answer:
Hi XXXXX,
Welcome to health care magic,
These numbers are actually the durations of the various waves that form a heart electrical activity.
QRS represents the duration of ventricular depolarisation.It actually represents the simultaneous activation of the right and left ventricles, although most of the QRS waveform is derived from the larger left ventricular musculature.
Its normal value is (QRS duration) 0.06 to 0.10 seconds i.e 100 milliseconds.In your case QRS 72 ms is completely normal.
The QT interval represents the duration from the depolarisation to the repolarisation of the ventricles. It begins at the onset of the QRS complex and ends at the endpoint of the T wave.
In simple words,QT is the time that the heart takes to recover from the major 'squeeze' .Its normal duration is QT Interval ≤ 0.40 sec.
Here,QT interval is 432 ms which slightly on a higher side.
Now,the important thing to remember is that an EKG's "numbers" are not necessarily indicative of a problem.They may be inaccurate for reasons of lead placement on your particular body and quality of the contacts.
It is therefore important that your doctor must make the interpretations of the TOTAL results which includes the wave shapes. This will determine if the QT interval is actually long.
However long QT is seen in conditions like slow heart rate,hypokalaemia, hypocalcaemia or in some myocardial diseases.
I would suggest you to take clinical interpretation of your EKG findings by your physician or cardiologist.
Thanks and Regards,
