SINUS TACHYCARDIA ECG CHANGES - HEART AND TECHY

Ecg changes in sinus tachycardia.


What is meant by tachycardia? Tachy 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, cardiac failure, in cardiac failure this arrhythmia mainly occur in as a result of increased Bainbridge reflex.

It is a normal accompaniment in fever, the sinus rate will increase by 8 beats per minute for every one-degree increase in temperature. What is meant by chronotropic incompetence? It is an inability to increase the heart rate according to our physiological need. for example, some people don't have an increase in heart rate during exercise to meet their body physiological need

ecg

Inappropriate sinus tachy is a clinical situation where sinus tachy is present without any identifiable causes. These are caused by either inappropriate increase of sinus node automaticity, this is an example of sinus tachycardia

carotid sinus massage or compression will help us to terminate this kind of arrhythmia

stay tuned with heart and techy..thank you...

PERICARDITIS ECG CHANGES - HEART AND TECHY

Image
  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  is the layer which is very close to pericardium,so  changes  which occur in  epicardium  in pericarditis will also a ffect   pericardium layers of the heart Majority  of perfusion occur in our  heart  during diastole.C hanges  in

RIGHT VENTRICULAR FUNCTION ASSESSMENT IN ECHOCARDIOGRAPHY-RIGHT VENTRICULAR SERIES PART-2

 RIGHT VENTRICULAR SERIES PART-2  RIGHT VENTRICULAR FUNCTION ASSESSMENT Why should we  measure   Right Ventricular   function  in the  echo? The right ventricle  has its  unique function  In our  first   part of  Right Ventricular series(RV SERIES) we  discussed  how to quantify  Right Ventricular size  in  echo Before going  to the lecture  we have  to know  there is some  limitation  for assessing Right Ventricle in  echo  because of the  crescentic shape , we had already  discussed  this in our  first   part of  RV series. Right ventricular function is mainly assessed by  5   methods: Tricuspid  annular plane   systolic excursion fractional area  change tei index s   prime visual  estimation  of RV  free wall  tricuspid  annular motion TAPSE   TAPSE is  measured  from Right Ventricle m mode. In  apical  four-chamber view m mode cursor  placed  on the  junction  of  tricuspid valve plane  with the RV  free wall.  Tapse is the  difference  in displacement during  diastole  and  systol

HEART AND TECHY-RIGHT VENTRICULAR SIZE AND FUNCTION ASSESSMENT ECHO-PART 1

Image
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 has traditionally been  evaluated  qualitatively by  2D  echocardiography. QUALITATIVE PARAMETERS TO ASSESS THE RV SIZE IN ECHOCARDIOGRAPHY: A standard apical four-chamber is best to assess RV size compared with t
