7/3/2023 0 Comments Normal cardiographThe PR segment represents the electrical conduction through the atria and the delay of the electrical impulse in the atrioventricular node. Make sure the lighting conditions are normal in the room or the place you are trying to use Cardiograph program or you will not get any reliable results. ![]() It is designed to be simple and accurate. This slowing signal appears as a flat line on the ECG between the end of the P wave and the beginning of the Q wave. Cardiograph is a program that allows you to measure your heart rate using your computer’s webcam. Divide 300 by this number to calculate heart rate. The signal slows down as it passes through this node, allowing the ventricles to fill with blood. Heart rate What’s a normal adult heart rate Normal: 60-100 bpm Tachycardia: > 100 bpm Bradycardia: < 60 bpm Regular heart rhythm If a patient has a regular heart rhythm their heart rate can be calculated using the following method: Count the number of large squares present within one R-R interval. The electrical signal passes from the atria to the ventricles through the atrioventricular (AV) node (2). The PR Interval is the time, in seconds, from the beginning of the P wave to the beginning of the QRS complex. This electrical signal is recorded as the P wave on the ECG. ![]() The electrical signal begins in the sinoatrial node (1) which is located in the right atrium and travels to the right and left atria, causing them to contract and pump blood into the ventricles. Electrocardiogram pattern of clopidogrel (0.2 mg/kg)-treated isoproterenol-induced group rats showing minimized ST-segment elevation. Look at the EKG/ECG to see if the rate is regular and how fast the heart is beating both are important for rhythm interpretation. ECG pattern of isoproterenol (100 mg/kg)-induced group rats showing pathological changes such as ST-segment elevation. This information is recorded on a graph that shows each phase of the electrical signal as it travels through your heart. ECG pattern of normal control group showing normal cardiograph. Keywords: electro-cardiographic, Aluminium phosphide, ethylene dibromide & poisoning.Also known as an electrocardiogram or an EKG, an ECG is a test that detects and records the strength and timing of the electrical activity in your heart. It was seen that even if ECG showed normal pattern there were significant histopathological changes in heart. Survivors of ethylene dibromide poisoning echocardiography was normal in 11 (84.61%) followed by pericardial effusion in 2 (15.38%) patients.Ĭonclusion: Noteworthy finding was absence of correlation between cardiovascular involvement, histopathological changes and ECG findings. The most ominous finding was arrhythmia which was associated with 100% mortality. However hyperkalemia was the most ominous finding associated with 100% mortality, ECG finding in EDB was normal ECG. ![]() ![]() Result: ST-T changes were most common finding in Aluminium phosphide poisoning in relation to mortality. Echo & Histopathological examination was done. Investigations had done included routine haematological examination, Biochemical analysis, urine examination, ECG, 2 D. cardiovascular, respiratory and gastrointestinal and nervous system. History was followed by a careful clinical examination i.e. Electro-cardiographic, Aluminium phosphide, ethylene dibromide & poisoning Abstractīackground & Method: The study was conducted in the Department of Medicine Shyam Shah Medical College and Associated Sanjay Gandhi Memorial Hospital, Rewa (M.P).
