A 21-year-old female asked:

I had tachycardia of 170 earlier in the hospital. a basic heart monitor showed vertical line qrs with basically an up sloping line between. the nurse printed it out but didn't seem concerned. could it be because the heart monitor is imprecise?

No...: The heart monitor is very precise. The nurse may not have been precise! it sounds like you may have had a supraventricular tachycardia (svt). Ask your doctor.

Need ECG: Although monitor can help determine arrhythmias, ECG is essential in accurate diagnosis of type of arrhythmia. Heart rate on 170 at rest is not normal and should be investigated. In a young adult who is otherwise healthy, the cause is most likely svt which could be curable. Best to see a cardiologist.

Arrhythmia: Sounds like you have any number of supraventricular tachycardias... Wpw, avnrt, atrial tachycardia... If left untreated it may lead to weak cardiac function. The specific arrhythmia you have can be easily diagnosed and cured by a cardiac electrophysiologist. Please request to see this particular field of doctor and not just a general cardiologist.
