The presentation and symptoms a patient can present with are varied and often dependent on the underlying cause of the junctional rhythm. Patient's can be asymptomatic for example, or experience difficulty breathing and chest pain if they have underlying congestive heart failure.
There are different types of heart failure; left- or right-sided (or bilateral) heart failure may occur depending on the affected part of the heart, and it is a low-output type of failure. If one of the heart valves is affected, this may cause dysfunction, such as mitral regurgitation in the case of left-sided coronary occlusion that disrupts ...
The underlying causes of sudden cardiac arrest can result from cardiac and non-cardiac etiologies. The most common underlying causes are different, depending on the patient's age. Common cardiac causes include coronary artery disease, non-atherosclerotic coronary artery abnormalities, structural heart damage, and inherited arrhythmias. Common ...
These maneuvers involves holding one's breath and bearing down—can be employed to stimulate the vagus nerve and slow the heart rate. [13] However, these techniques may provide only temporary relief, and if palpitations persist or are associated with other concerning symptoms, medical evaluation is essential to determine any underlying causes ...
Treatment depends on the type of heart rhythm shown on an electrocardiogram test, and the stability of the patient's blood circulation. If a patient has low blood pressure, difficulty breathing, chest pain, shock, or confusion, they are considered unstable and must have an electrocardiogram result checked to determine if the heart is beating ...
This can happen as a result of exercise (physiological remodeling) or after injury to the heart muscle (pathological remodeling). [2] The injury is typically due to acute myocardial infarction (usually transmural or ST segment elevation infarction), but may be from a number of causes that result in increased pressure or volume , causing ...
Treatment depends on the type of cardiomyopathy and condition of disease, but may include medication (conservative treatment) or iatrogenic/implanted pacemakers for slow heart rates, defibrillators for those prone to fatal heart rhythms, ventricular assist devices (VADs) for severe heart failure, or catheter ablation for recurring dysrhythmias ...
These devices, usually implanted under the skin at the front of the chest below the shoulder, can continuously monitor the heart for abnormal heart rhythms. If a life-threatening arrhythmia is detected, the device can deliver a small electric shock to terminate the abnormal rhythm and restart the heart.
