Hi I am 27 year old yesterday I have done ecg in that qt and qtc range are 334 and 457 please tell me I have any heart problems please suggest me.

Question

Hi lybrate-user Only based upon QT and Qtc range, we can't predict the heart condition. We need to have your other parameters too, Because all parameters are required to know down the ECG problems, as diagnosis or conclusion is permutations and combinations of various ECG data, QT changes diagnosis will change with other associated information, preferably a photo of your ECG will help us more. Also We should know -your health status, (over weight, heavy, lean etc) -eating and drinking habbits, - smoking habbits - current health problems- for what you doing Ecg (like chest pain, discomfort etc) - blood pressure status - h/o any MEDICATION (some drugs interfere in QT interval) - h/ O hypertension or diabetes etc So we need more data for more detailed evaluation. In cardiology, the QT interval is a measure of the time between the start of the Q wave and the end of the T wave in the heart's electrical cycle. The QT interval represents electrical depolarization and repolarization of the ventricles. A lengthened QT interval is a marker for the potential of ventricular ¿'arrhythmias, etc. Modern computer-based ECG machines can easily calculate a corrected QT (QTc), but this correction may not aid in the detection of patients at increased risk of arrhythmia, as there are a number of different correction formulas. So please get back to us for more information on this.

Normal QTc values. QTc is prolonged if > 440ms in men or > 460ms in women. QTc > 500 is associated with increased risk of torsades de pointes. QTc is abnormally short if < 350ms. A useful rule of thumb is that a normal QT is less than half the preceding RR interval.
