physical examination during a PSVT episode will show a rapid heart rate. The heart rate may be 150 to 250 beats per minute (bpm). In children Cheap Victor Rask Hat , the heart rate tends to be very high. There may be signs of poor blood circulation such as lightheadedness. Between episodes of PSVT, the heart rate is normal (60 to 100 bpm). An ECG during symptoms shows PSVT. An electrophysiology study (EPS) is often necessary for an accurate diagnosis and to recommend the best treatment. Because of the sporadic nature of the PSVT, its diagnosis may require 24-hour Holter monitoring. For longer recording periods, a “loop recorder” (with computer memory) is used.
How should you treat PSVT.
If symptoms occur or if you have another heart disorder Cheap Scott Darling Hat , treatment may be necessary. If you have an episode of PSVT, a technique called the Valsalva maneuver can be used to interrupt the fast heartbeat. Hold your breath and strain, as if you were trying to have a bowel movement, or cough while sitting with your upper body bent forward. Splashing ice water on the face has been reported by some people as helpful.
Emergency treatment of PSVT may include:
Electrical cardioversion Cheap Elias Lindholm Hat , the use of electric shock to restore a rapid heartbeat back to normal. Medicines through a vein, including adenosine and verapamil. Other medications may be used, such as procainamide, beta-blockers Cheap Brock McGinn Hat , and propafenone.
Long-term treatment of PSVT may include:
Daily medications such as propafenone, flecainide, moricizine, sotalol Cheap Sebastian Aho Hat , and amiodarone. Pacemakers to override the fast heartbeat; very occasionally used in children with PSVT who have not responded to any other treatment. Radiofrequency catheter ablation; currently the treatment of choice for most PSVTs. Surgery to change the pathways in the heart that send electrical signals; this may be recommended in some cases for people who need other heart surgery.
