ارجع اعيد عليكم هاي المعلومة الي ناشرهة ببوست قديم ///
طبعًا المريض جانوا امشيلة adenosine والسيينير معتبرة SVT ..
ECG findings:
Regular 150 beats and “Saw-tooth” pattern of inverted flutter waves in leads II, III, aVF
فالجواب هو Atrial flutter
طبعًا اكو خطأ دا يصير انو البعض عبالهم ال Saw-tooth تبين بكل الليدات وهذا خطأ
هي فقط تبين بالانفيرير ليد و V1 …
طبعًا يعالج ك AF
نقاط مهمة عن Aterial flutter::
ECG features of atrial flutter::
• Narrow complex tachycardia
• Regular atrial activity at ~300 bpm
• “Saw-tooth” pattern of inverted flutter waves in leads II, III, aVF
• Upright flutter waves in V1 that may resemble P waves
• Ventricular rate depends on AV conduction ratio (see below)
Fixed AV conduction ratio (“AV block”):
• 2:1 block = 150 bpm
• 3:1 block = 100 bpm
• 4:1 block = 75 bpm
Variable AV conduction ratio::
• The ventricular response is irregular and may mimic (AF)
• On closer inspection, there may be a pattern of alternating 2:1, 3:1 and 4:1 conduction ratios
Classification:
Typical atrial flutter (common)
Anticlockwise Reentry: Commonest form of atrial flutter (90% of cases). Retrograde atrial conduction produces:
• Inverted flutter waves in leads II,III, aVF
• Positive flutter waves in V1 — may resemble upright P waves
Clockwise Reentry: This uncommon variant produces the opposite pattern:
• Positive flutter waves in leads II, III, aVF
• Broad, inverted flutter waves in V1
