RIGHT VENTRICLE SIZE AND FUNCTION IN ECHOCARDIOGRAPHY The right  ventricle   is a  complex   three-dimensional shape.  Echocardiographic assessment of the  right ventricle  is  more   difficult  than that of left ventricle because of the  complex geometry  and is  divided   into two   parts : the inflow tract and the outflow tract,  separated  by the crista supraventricular. Echocardiographic  imaging of  RV  function and  measurement  of ejection fraction has been  difficult  because of the  complex form  and  motion pattern  of the  RV  and  problems  with defining the  endocardial surface  of the  thin  RV  free wall.  Another important factor that complicates the interpretation of RV  function  is the varying  loading conditions.  In daily cardiology practice, RV function...

  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 ...

HEART RATE   CALCULATION  IN  ECG-HEART AND TECHY First of all  we are  discussing  about  rate  of  e c g paper ,Before  calculating   heart rate  from an  e c g  you have  to know  what is  meant  by  standardisation  in an  e c g paper X  axis of the  paper  denotes the  time  and  Y  axis denotes the  amplitude.One   large box  in an  e c g paper  contain  25   small boxes  totally that is  5   small boxes  in  x  and  5   small boxes  in  y  axis. In x axis  duration of  one  small box  is 0.04  second  ,so  duration of   5   large box  is 0.2 second.In Y axis amplitude of one  small box  is 0.1 millivolt and  5   large box  is 0.5 millivolt, first step  while  reading ...

Add caption DIURETICS-CARDIOVASCULAR DRUGS   Diuretics   lower   blood pressure  by  increasing  the  kidneys   excretion  of  sodium  and  water ,which in  turn   reduces  the  volume  of  blood These are the  older   antihypertensive   agents , The   diuretics  are  classified  according to the  site  of  action  in the  kidney ,Thiazide diuretics  work  in the  tubules Loop   diuretics  are more potent than  thiazide  diuretics,They are usually  prescribed  when thiazide diuretics proves to be  insufficient  for  patients  with  heart failure Potassium  sparing diuretics  work  in the  area  were  potassium  is  excreted,Diuretics  are the  class  of  drugs  which are  less   expensive  in...
