Heart & Techy

  SINUS TACHYCARDIA ECG CHANGES - HEART  AND TECHY E cg changes in   sinus tachycardia. What is  meant  by  tachycardia? T achy  means   increasing   heart rate   more  than  100   beats  per  minute , before going  to discuss  about this topic we have  to know  what is  meant  by  sinus rhythm , you can refer this topic in my  previous video , the  link  is here https://www.youtube.com/watch?v=zSgITZ98bOM In sinus tachy, there is no  conduction   related  abnormality present. Only the  P, QRS  and T complexes  recorded   in   rapid  succession. sinus tachy is a  normal physiological response  during  emotion ,  respiration ,  exercise But some  cases  sinus  tachycardia  also occur in some  pathological conditions  such as  thyrotoxicosis, toxaemia,  card...

  SINUS ARRHYTHMIA-HEART  AND TECHY-ECG CHANGES W hat is meant by  sinus arrhythmia, what are the ecg changes associated with sinus arrhythmia..before going to that you have  to know  what is  meant  by  normal sinus rhythm? ...... These  are  the criteria for  diagnosing   normal sinus rhythm ........... A  regular rhythm  at a  rate  of  60  to  100   beats  per  minute Each  p wave  is  followed by  a qrs complex P wave   will  be  upright  in  leads II, III,  a  v  f and  lead   1  and a v l,  negative  in a  v r  and biphasic in  v   1   why  the  p   wave  have different morphology in  different leads? I  had already prepared a video-based upon the  right  and  left   atrial enlargement , you can refer thi...

  PERICARDITIS ECG CHANGES-HEART AND TECHY P ericarditis  is the  inflammation  of pericardium. Pericarditis Acute pericarditis is  caused  by  infective , autoimmune,neoplastic,  radiation injury  or  metabolic causes. Virus Viral infection  is the most common  cause  of pericarditis.Pericarditis in  acute myocardial infarction  is  due  to local pericardial inflammation. Main   ecg   changes  in pericardial effusion are PR  segment depression  and ST segment  elevation virus ST segment elevation is occur  due   to change  in  epicardium,this  exerts a  pressure  in our  heart  which will  result in   decreasing  contractility,decrease filling and  decrease   cardiac output. Our  heart  consist of  3  layers, epicardium myocardium and  endocardium,epicardium ...
