that Kearsley had an atrial fibrillation (an irregular heartbeat) and refused to pass him. Kearsley took it upon himself to consult a medical specialist who advised him that his condition would indeed not affect his ability to perform his job as a firefighter. Kearsley then filed a complaint against the city with the Ontario Human Rights Commission. At the Commissions Bored of Inquiry hearing‚ the doctor who had originally examined Kearsley testified that atrial fibrillation led to increased risk

MUSCULOSKELETAL FRACTURES ● Fracture is a disruption or break in the continuity of the bone structure. ● Traumatic injuries account for the majority of fractures. ● Fractures can be classified as displaced (open) or nondisplaced (closed) depending on communication or noncommunication with the external environment. ● Signs include immediate localized pain‚ decreased function‚ and inability to bear weight or use affected part. Obvious bone deformity may be present. ● Bone goes through eight stages of selfhealing (union)

Depolarization of the atria on an ECG can be seen as the P wave (Figure 1). During atrial systole‚ the blood is pushed through the atrioventricular (AV) valves into the ventricles and the impulse will reach the AV node just shortly after. This slight delay from the SA node to the AV node allows the ventricles to completely fill with blood

at improving general well-being while also involving specific protection for selected diseases. Primary prevention of stroke includes lifestyle modifications and measures to control blood pressure‚ cholesterol levels‚ diabetes mellitus‚ and atrial fibrillation. Lowering blood pressure in patients with hypertension prevents both types of stroke‚ which are hemorrhagic and ischemic stroke. Hemorrhagic stroke is caused by the rupture of blood vessels in the brain. Ischemic stroke‚ which is the most common

of irregular heartbeats is medically referred as Arrhythmias [1].Examples of arrhythmias conditions include AV Nodal Reentrant Tachycardia‚ Atrial Fibrillation and Atrial Flutter[3]. Arrhythmias is usually treated by medication but in case it is not effectively treated by medication or the patient lie under a high risk of atrial or ventricular fibrillation‚ then a cardiac ablation procedure is performed [4].

Allows completion of atrial contraction before initiation of ventricular systole. 2. Even though cardiac muscle has an inherent ability to beat. the nodal system plays a critical role in heart physiology. What is that role? Ensures that depolarization proceeds in an orderly

* GROUP 2: Elrey Joseph Calitis Mae Anjneth Cuaton How Atrial Tachycardia happens? Electrical signals in the heart’s upper chambers fire abnormally‚ which interferes with electrical signals coming from the sinoatrial (SA) node --- the heart’s natural pacemaker. A series of early beats in the atria speeds up the heart rate. The rapid heartbeat does not allow enough time for the heart to fill before it contracts so blood flow to the rest of the body is compromised. Video Presentation

Warfarin is given for 3-4 weeks before cardioversion and at least 4 weeks after cardioversion. Direct oral anticoagulants are non-inferior to warfarin and can be used alone in non-valvular atrial fibrillation. They should not be given with warfarin‚ heparin or to patients with prosthetic valve or end stage renal disease. Examples include‚ Direct thrombin inhibitors
