Thank you for your comment! So glad it was useful for you. I have 2 other ECG videos on my channel (ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-ERLT62dhsk0.html / ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-55JGS96YZps.html) which may also help you.
what about a slightly wide QRS heart ryth(via Kardia mobileapp.) ? normal sinus rhythm(regular P waves) with wide QRS, good BP. good O2 saturation heart rate of 70 bpm...always 110/70 pressure. 59 year old male (former experienced Emergency medical tech.)
The doctor dug through old test reports and said my mum always had abnormal ECG ever since she was in her 20s and that it's a normal thing for her. She is 60 now. How can an abnormal heart reading be normal???
Thanks for watching. I have covered PR intervals in a separate ECG interpretation video (ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-ERLT62dhsk0.html). Skip to 09:50 for PR interval section. Hope that helps!
