1. INTRODUCTION 1.1 ECG BASICS Fig.1.1 Human Heart ECG’s dictate the electrical impulses of the heart Electrical impulses are what make the heart contract This contraction is also known as depolarization and repolarization is Relaxation of cells after depolarization. COMPONENTS OF ECG MACHINE Black and white on front limbs (B=Left/W=Right)-Placed at the elbow region. Green and red on back limbs (G=Right/R=Left)-Placed at the stifle region .Alcohol, ECG paste or ECG pads can be used as conduction agents for more accurate readings. If your patient has long hair, it should be shaved at the site of cable placement in order to achieve adequate conduction in addition to the use of a conduction agent. SOLID GROUND Having the ECG machine well grounded is an important factor for obtaining an accurate reading. Placing the patient on a rubber mat and ensuring that the machine is plugged into a grounded outlet as well as checking the ECG machine for loose wires or cracked insulation on wires are steps that can be taken for a good ground. LEADS Lead I: causes right forelimb to become a negative pole and the left forelimb to become a positive pole. Lead II: causes right forelimb to become negative and left rear limb to become positive. Lead III: the left hind limb becomes a positive pole and the left forelimb becomes a negative pole. Fig.1.2 Lead Configuration In the present mechanized age, globalization has influenced the medical field as well. At present most of the popular diagnostic centres and hospitals globally are being habituated in exchanging of bio-medical information through wireless media for mutual availability of therapeutic case studies as well as for improvement of diagnostic results. This communication of exchanging medical data through wireless media requires high security and authentication . This concept of telemedicine basically and
