Cardiac electrophysiology

Dunk Summarize: A 22-year-old male, Joe Hamilton, suffered a cardiac arrest while playing basketball. Consequently, responders proceeded with cardiopulmonary resuscitation and electrical defibrillations that lead to a pulse return, however Joe remained in a coma. Ask: What is a normal ECG and how do you read it? Access/Generate: After Joe Hamilton’s cardiac arrest, an AED was placed on his chest and proceeded to analyze his cardiac rhythm (see Figure 1) and returned an inadequate rhythm. Figure

plethysmograph is not a direct measure of pulse pressure, its wave is created by blood flow, so it can so it still provides information about blood pressure and the circulatory system. The plethysmograph graph provides information related to hypertension and cardiac output (Grote et al., 2003). As shown in figure 3a, heart rate was higher when sitting than when prone. When the subject stood up, blood began to move to lower extremities due to gravity and to support the leg and foot muscles. This is not present

Q- waves are a sign of previous myocardial infarction. The Q wave is defined as the first downward deflection after the P wave. It may be present and it can be absent in a normal ECG. The Q wave represents the depolarization of the interventricular septum. Never to be considered abnormal if it is missing from any particular lead.The QRS complex is a name for the combination of three of the graphical deflections seen on a typical electrocardiogram. The Q wave is usually the central and most visually

Brady Arrhythmias is any disruption of cardiac rhythm resulting in 60 heartbeats per minute or less. However, it should be noted that 60 BPM is normal heart rate for young adults and athletes. There are multiple possible causes including heart tissue damage, hypothyroidism and inflammatory diseases: Risk for Brady Arrhythmia increases due to age, smoking and high blood pressure. Effects include fainting or feeling faint, fatigue and chest pains. Treatment depends on the severity of symptoms ranging

1. Introduction The electrocardiogram (ECG) is one of the most widely used tools for non-invasively assessing the cardiac state of a subject. It is used internationally for the early detection of acute myocardial infarction and arrhythmias such as atrial fibrillation [1]. Due to the high mortality rate of cardiovascular disease (CVD) it is of paramount importance to optimise the use of the ECG as it detects the presence of CVD. The World Health Organisation estimates this disease will kill approximately

Not measurable QRS: (.1 pt.) none QT: (.1 pt.) 8 sec Rhythm: (.3 pt.) highly irregular b. What is the necessary immediate intervention? (.1 point) The next action for this patient is to defibrillate very soonest to stop the patient from going to cardiac arrest c. What are two typical precipitating factors that occur with this rhythm? (.1 pt.) i. Is having an untreated ventricular tachycardia, electrocution accidents and presents of heart conditions at birth. ii. Chaotic, rapid and irregular rhythms

They are different kind of forms the P wave it represents depolarization. It indicates atrial depolarization, or contraction of the atrium. Normal duration is no longer than 0.11 seconds less than 3 small squares. Amplitude height is no more than 3 mm. No notching or peaking. The PR interval represents the time impulse initiated by the sinus node travels through the atria to the ventricular conduction system. PR interval indicates AV conduction time. The duration time is 0.12 to 0.20 seconds. The

Primary Target Keyphrase: identifying Afib 1. When you feel that your heart is racing even when at rest, then it is a heart rhythm disorder known through identifying Afib. This can also happen to healthy heart. 2. You can know the condition of your heart by identifying Afib where the small chambers pumping blood to the larger ventricles begin to quiver erratically causing increased heart rate. 3. If you measure the heart beat by identifying Afib, then you will come to know that the heartbeat has

excitation wave which will re set the heart at a sinus rhythm. Pacemakers act as signal transmitter that interprets the electrical signal then decides whether to initiate another signal such, as if the heart electrical signal was blocked it would lead to cardiac arrest however the pacemaker picks up that no electrical signal has been initiated and therefore generates one in order to keep the heart pumping. In addition to these pacemakers have special sensors that pick up when you are moving and your respiration

INTRODUCTION Heart diseases are one of the most life threatening disease in the world now a days. The common method for diagnosing cardiac diseases is ECG. ECG is simple, non-invasive and cost effective tool for diagnosing purpose. It is important to classify the beats properly to find out the arrhythmia. Classification of heart beat is tedious and time consuming job therefore there
