What is the normal QTC for holter 24h registration?
I had holter two times last months and the results are:
Max QT = 434 ms (65 bpm at 11:19 pm)
Max QTc = 459 ms
Max QT = 428 ms (60 bpm 01:53 am)
Max QTc = 465 ms
I take bisoprolol 2.5 mg and magnesium.
1. Should I consider Prolonged QTc Interval?
2. How can I reduce QTc interval?
3. Can I take medicines which extend Qtc interval?
I am 28 years old male.
