  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 inspiration. I

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. Tamil video: https://youtu.be/61TVnD2xeYs English video: https://youtu.be/pJ3wEGcw7OY                             HOW TO  INTERPRET AN ECG:          STANDARD ECG: In standard ECG there are 10 electrodes .   4 limb electrodes – left arm and leg ,right arm and leg. 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 towards the positive electrode Each electrode will detect any wave of positive charge coming around them. 12 LEAD E

Hello everyone. In today's topic we are going to discuss about the basic information about the Electro cardiogram (ECG).    The content is available in video forms in Tamil and English. If you have any doubts please post in the comment section . ENGLISH :  https://youtu.be/DQNFPnDpbxA TAMIL : https://youtu.be/1RgN1gnOJ60    INTRODUCTION:          ECG is the tool used to visualize the electricity that flows through the heart        In the body ,tissues and fluids conduct electricity well. That’s why  the electrical activity in the heart can be recorded on the skin surface using electrodes which are   positioned on the limbs and the chest.         This recording is  called an electrocardiogram(ECG) which shows the spread of the electrical signal which are generated by the SA node as it travels through the atria, the AV node and the ventricles.  The normal ECG  shows five waves which, are P, Q, R, S and T.   PQRST WAVES: The P wave arises when the impulse from the SA node travels over

                     Hello friends .. In today's topic we are going to discuss about " THE CARDIAC CYCLE". If you have any doubts please post in the comments section below . I have also made the content in a video in Tamil and English .I'm giving the link below.. YOU TUBE CHANNEL LINK: https://www.youtube.com/channel/UCZrabu-CtMa5AEexu1j2GNw ENGLISH VIDEO :  https://youtu.be/SkqabJmffEc TAMIL VIDEO: https://youtu.be/DSzgU4vaVwc     INTRODUCTION:         The healthy adult heart  beats at a rate of 60–80 beats per minute at rest. Stages of the cardiac cycle: • In Atrial systole – contraction of the atria takes place. • In ventricular systole – contraction of the ventricles takes place. • In complete cardiac diastole – relaxation of the atria and ventricles takes place. During each heartbeat also called as cardiac cycle the heart contracts (systole) and  relaxes (diastole). Taking 74 beats per minute as an example, each cycle lasts about 0.8 of a second. ATRIAL SYSTOL
