איזו הפרעה -זו שנקראת - svt ?

Sorry for the English, i am on an American type computer now... SUPRAVENTRICULAR TACHYCARDIA - SVT An SVT type rhythm disorders result from rapid heart pulse, derives from the heart’s atrium. Several mechanisms that may elicit this heart disease exist. The most common mechanism is caused by an additional conduction fiber in the heart’s muscle next to the AV Node. Due to this fiber, an electrical circuit is formed between it AND the heart’s normal conduct system. As a result, a 180 BPM rhythm disorder is formed (while 70 BPM counts as normal). In rare occasions, the BPM can reach even to 250 BPM. The patient will usually feel this heart rate that may be accompanied with dizziness, asthma, chest pains AND in some cases, loss of consciousness. This irregular heart rate continues for hours AND hospitalization may be adequate. In the emergency room, in most cases, the cardiologist injects the vain Adenosine. This drug reaction time is very fast AND stops the rhythm disorder immediately. The medication’s side effects are fever sensation AND momentary fatigue. The patient will be directed to an Electrophysiologist to be diagnosed through an Electrophysiological examination. Usually, the Electrophysiologist will “burn” the additional fiber’s conduct path with the ablation procedure. Another less common mechanism for this condition is an additional fiber that is found at the Accessory pathway. This fiber may cause an even faster heart rate than the previous mechanism- up to 300 BPM. In these rare cases, the patient may experience cardiac arrest. Here, as well as before, the patient must arrive to the emergency room at a near hospital. Again, the ablation procedure will be conducted.

פירוש המושג הוא הפרעת קצב על חדרית - זהו של כולל לכל הפרעות הקצב שמקורן בעליה או במערכת ההולכה שבין העליה לחדר. בד"כ השמוש בשם SVT מכוון להפרעת קצב הנובעת ממסלול חשמלי עודף הנמצא בין העליה לחדר וקיומו מאפשר אירועים של דופק מהיר שלא נשלט ע"י מערכת הבקרה של הלב. הטיפול המידי הוא תרופתי (במקרים נדירים יש צורך מהיפוך חשמלי) ובמקרים של אירועים חוזרים יש צורך באבלציה (צריבה) תודה
