  Hello everyone, In today's topic we are going to discuss about the what a standard 12 Lead ECG and how to interpret it in a simple 6 steps. I have made this content in a video format in Tamil and English. If you have any doubts kindly post in the comment section below. TAMIL VIDEO: https://youtu.be/c1bxvGsCWKM ENGLISH VIDEO: https://youtu.be/XfdchDKLS20 INTERPRETATION OF ECG: ECG PAPER: ECG paper is divided into large square with 5mm wide and these large squares are further subdivided into small squares of 1mm width. The ECG machine mostly runs at 25millimeter / second. There are five small squares in one large square.  Small squares equals one minute (1500 x 0.04 = 60 seconds).  1 small square =0.04 seconds 1 LS = 0.2 seconds. 5 LS = 1 Second  30 LS = 6 Seconds. We can also count the number of small squares in between 2 R waves and calculate the heart rate / minute. 1500 /n = heart rate / minute. But usually the heart rate slows during expiration and speeds during...

Hello everyone, In today's topic we are going to discuss about the what a standard 12 Lead ECG is about and through by a glance of ECG how we can interpret which area is affected. I have made this content in a video format in Tamil and English. If you have any doubts kindly post in the comment section below.

In where right leg is a neutral lead. 6 Precordial electrodes. i.e. V1,V2,V3,V4,V5,V6 which are placed around the chest. Heart is a 3 dimensional organ .so V1-V6 are lined in a transverse or horizontal plane of the chest.  The electrodes detect the charge outside the cells. Usually the dipole will be more ...
