Atrial Fibrillation/Atrial Flutter

  Atrial Fibrillation  Atrial Flutter Atrial Fibrillation   (Afib) Afib stands for atrial Fibrillation (AF) Atrial Fibrillation is a type of arrhythmia or abnormal heart beat and is a major cause of stroke.  Atrial Fibrillation is an irregularly irregular and often very rapid heart rhythm that begins in heart upper chambers (Atria). in which the upper chambers of the heart (atria) beat out of coordination with the lower chambers of the heart (ventricle). ATRIAL FIBRILLATION FINDINGS ON ECG Findings Irregularly irregular QRS Complex P wave absent / no visible P wave present Heart beat range (100bpm - 160bpm) Types of Atrial Fibrillation There are three main types of atrial fibrillation.... Paroxysmal atrial Fibrillation Persistent atrial fibrillation Long standing persistent atrial fibrillation Paroxysmal Atrial Fibrillation It's episodes occurs less than one week and usually stops on its own without treatment. Persistent Atrial Fibrillation It's episodes occurs more than one we

HUMAN CIRCULATORY SYSTEM/BLOOD VASCULAR SYSTEM

HEART CIRCULATORY SYSTEM OR  BLOOD VASCULAR SYSTEM The study of blood vascular system or circulatory system is called angiology    The vascular system is made up of the vessels that carry blood and lymph fluid through the body. It's also called the circulatory system. The arteries and veins carry blood all over the body. They send oxygen and nutrients to the body tissues.   BLOOD VESSELS 1  Arteries  2  Veins 3  Capillaries Differentiate between arteries and vein  CAPILLARIES They have only one layer i.e. simple squamous endothelium layer.  ANATOMY OF HEART Heart  is a coned shaped hollow structure equal to the size of puzzle fit. It is a mesodermally derived organ, is situated in the thoracic cavity, in between the two lungs (mediastinum), slightly tilled to the left. The heart weight between 200 to 425g.  The lower portion is apex and upper portion is base. Wall of heart  1.  Pericardium 2.  Myocardium 3.  Endocardium Pericardium--  It is a outermost layer of the heart. Heart is

ECG Interpretation/ How to read an ECG or EKG/ Characteristics of the normal ECG

  ECG INTERPRETATION BASIC  An ECG complex represents the electrical events occurring in one cardiac cycle. A complex consists of five waveforms labelled with the letters P, Q, R, S, and T. The middle three letters —Q, R, and S—are referred to as a unit, the QRS complex. ECG tracings represent the conduction of electrical impulses from the atria to the ventricles.    P WAVE  Small, Positive and smooth wave. Always +ve in lead II during sinus rhythm. P wave is virtually always +ve in leads aVL, aVF, I, V4, V5, and V6 and -ve in aVR lead. Frequently biphasic in V1 ( occasionally in V2)  the -ve deflection is normally <1mm. P wave duration should be < 0.12 sec. P wave amplitude should be <2.5 mm.

ELECTROCARDIOGRAPHY BASIC

  What is electrocardiography (ECG) Electrocardiography is a medical test in which diagnose cardiac disorder i.e. MI (myocardial infarction) etc. by measuring the electrical activity of the heart via electrodes placed on the limbs and chest wall and are transcribed on to graph paper to produce an electrocardiogram and also known as ECG/EKG.                                     OR     Electrocardiogram   Electro means electrical activity   Cardio means heart   Gram means graphical representation   An electrocardiogram is a graphically representation of an electrical activity of the heart and used in the investigation of heart disease.   The device is used is known as electrocardiograph.   NOTE -- The term electrocardiogram was introduced by Willem Einthoven in 1893   Later in 1924 Einthoven received the Nobel prize for his life's work.       Indication of ECG (Why it's done) Due to cause of chest pain, palpitation, Dizziness, shortness of breath and wea
