The Electrocardiogram 2IntroductionHannibal, G (2009); Moses, et al., (2008) defines electrocardiogram as the graphical representation of the electrical conduction of the heart muscles. This is achieved by attaching electrodes to the body surface. It is a tool for diagnosis and management of any cardiac rhythms that are abnormal. It can also be used in the diagnosis of the causes of chest pain. Thrombosis management of myocardial infarction depends on it. It can also be used in identifying the causes of breathlessness in a patient (Hampton, J 2013). An electrocardiogram for easy interpretation can be grouped into segments, waves, and intervals.P, Q, R, S, T, U waves. The QRS complex segment, PR segment, and ST segment. RR interval, QRS complex interval, PR interval, QT interval and ST interval. A deviation on any of the aboveis indicative of a problem in cardiac muscles electric conduction (Davidson, 2014). In electrocardiogram interpretation the following factors are analyzed; rhythm, conduction interval, cardiac axis, description of ST segment, QRS complexes and the T waves (Hampton, J 2013). Electrocardiogram (ECG 1)a)There is a normal sinus rhythm with a heart rate of 50beats/minute because;Every cycle starts with a P wave, a QRS complex follows the P waves. The PR intervals remain the same. This shows that the electrical conduction starts at the Sinoatrial node. The heart rate is regular and bradycardic. b)There is a normal cardiac axis.The ventricular depolarization that is seen on the front is called cardiac axis. It is deduced from the interpretation of the QRS complexes on lead I, II, III. A normal cardiac axis looks like a
The Electrocardiogram 3clock moving from 1100hrs to 0500hrs. The deflections on these leads are usually upright. For a normal cardiac axis, the lead II is more positive than the rest (Currey et al., (2005). All of them shows a positive deflection and the lead II deflection is most positive.c)Prolonged PR interval 240ms.PR interval is measured from the start atrial depolarization that is the P wave to the start of ventricular depolarization that is QRS complex. The normal ranges are 120ms-200ms.d)The QRS segment is normal.A representation of ventricular depolarization. Has the Q, R, S waves. In V1, V2, V3, and V4 theS waves are deeper than the R waves which is normal. V5, V6 the R waves are longer than S waves which are normal.e)QRS interval is normal, 120ms.This represents the ventricular contraction, both the left and the right ventricles. It should not 120milliseconds. f)ST segment is normal.It is isoelectric that is, it lies on the same level as the sections between the T waves and that of the subsequent P wave. It is an indication of sufficient cardiac muscle perfusion.Interpretation This is indicative of first-degree heart block. This is because each depolarization wave originates from the Sino-atrial node, P wave. The P waves atrial depolarization) is followed by aventricular depolarization QRS complex wave. This is conduction in the ventricles.
