Some people don’t experience any symptoms at all. Symptoms common in several types of cardiovascular disease include: Shortness of breath. Chest pain. Fatigue. Dizziness. Fainting. Fever ...
Causes: Not known [3] Risk factors: Alcohol, caffeine, nicotine, psychological stress, Wolff-Parkinson-White syndrome [3] Diagnostic method: Electrocardiogram [3] Prevention: Catheter ablation [3] Treatment: Valsalva maneuver, adenosine, calcium channel blockers, synchronized cardioversion [4] Prognosis: Generally good [3] Frequency: 2.3 per ...
Synchronized electrical cardioversion is used to treat hemodynamically unstable supraventricular (or narrow complex) tachycardias, including atrial fibrillation and atrial flutter. It is also used in the emergent treatment of wide complex tachycardias, including ventricular tachycardia , when a pulse is present.
Ionizing radiation may be used to treat other cancers, but this may, in some cases, induce a second form of cancer. [74] Radiation can cause cancer in most parts of the body, in all animals, and at any age, although radiation-induced solid tumors usually take 10–15 years, and can take up to 40 years, to become clinically manifest, and ...
Defibrillation or cardioversion may be accomplished by an implantable cardioverter-defibrillator (ICD). Electrical treatment of arrhythmias also includes cardiac pacing. Temporary pacing may be necessary for reversible causes of very slow heartbeats, or bradycardia (for example, from drug overdose or myocardial infarction).
Studies have been performed on the use of shortwave radiation for cancer therapy and promoting wound healing, with some success. However, at a sufficiently high energy level, shortwave energy can be harmful to human health, potentially causing damage to biological tissues, for example by overheating or inducing electrical currents.

Junctional tachycardia is a form of supraventricular tachycardia characterized by involvement of the AV node. [1] It can be contrasted to atrial tachycardia.It is a tachycardia associated with the generation of impulses in a focus in the region of the atrioventricular node due to an A-V disassociation. [2]
Patients should try to schedule the exam at a time when they will be having symptoms and will not need to drive for 2 to 3 days. If the reason for the EP study is for an arrhythmia, then antiarrhythmic drugs may be held to increase the likelihood of being able to induce the rhythm.
