התפשטות הגירוי החשמלי בלב

מנגנונים בסיסיים לכל אורך מערכת ההולכה יש תאים בעלי פוטנציאל קוצב ככל שהמוקד גבוה יותר הקצב מהיר יותר ESCAPE VS ECTOPY (ACTIVE VS PASSIVE ) הולכה בחדרים לאורך מערכת ההולכה הטבעית היא המהירה ביותר ולכן ה QRS הוא הצר ביותר QRS צר - מקור הקצב מ AV NODE ומעלה QRS רחב – מקור בתוך החדרים או הולכה אברנטית (ABERRANT CONDUCTION)

מקורות אפשריים לקצבים סינוס עליות (מחוץ לסינוס) AV NODE (NODAL, JUNCTIONAL ) חדרים

גישה כללית לאבחנת הפרעת קצב Rate (ECG blocks) Regularity P wave morphology P:QRS ratio QRS width

קצב סינוס תקין משבצת קטנה (1 מ"מ) – 40 מ"ש, משבצת גדולה = 200 מ"ש 5 משבצות גדולות = קצב 60, 4 משבצות = קצב 75, 3 משבצות = קצב 100, 2 משבצות = קצב 150, משבצת אחת = קצב 300 Cycle Length (msec) = 60,000/rate (bpm)
