陳文鍾教授現場指導 Sinus rhythm Left axis deviation LA enlarge Rule out LVH Poor R wave progression 當看到怪的 TWI 在 V1-V6, 除了 poor R wave progression 外, 也要考慮 lead position 可能代表嚴重的 LVH, 也可能是 old anterioinferior MI 7
8
EKG Interpretation Sinus rhythm with VPCs Left axis deviation R wave, V1-V6 LVH ST-T change at V1-V6 9
10
EKG Interpretation NSR, with frequent VPC T wave inversion at V1-V6 Rule out pulmonary hypertension Not suggestive for pulmonary embolism May be masked by LVH 11
Subsequent Course Consult CV man Echocardiogram D shape LV, RV McConnell's sign Dilated right heart TR, moderate to severe Chest CT McConnell s sign, that is regional RV dysfunction, with akinesia of the mid free wall but normal motion at the apex is a distinct echocardiographic finding described in patients with acute pulmonary embolism. Pulmonary embolism at bil. superior and inferior lobar arteries Patchy consolidation and peribronchial infiltration at the RML and left lung Cardiomegaly 12
Supplementary Material: What is McConnell s sign? Echocardiographic pattern of RV dysfunction consisting of akinesia of the mid free wall but normal motion at the apex 77% sensitivity and 94% specificity for diagnosis of pulmonary embolism 13
Supplementary Material: Echocardiographic Features of RV Dysfunction in Acute Pulmonary Embolism? RV wall hypokinesia Moderate or severe McConnell s sign RV dilatation End-diastolic diameter >30 mm in parasternal view RV larger than LV in subcostal or apical view Increased tricuspid velocity >26 m/sec Paradoxical RV septal systolic motion Pulmonary artery hypertension Pulmonary artery systolic pressure >30 mmhg Dilated IVC with lack of respiratory collapse 14
Subsequent Course Heparin 25000U in N/S 250ml, run 12ml/hr Admission 5CVI EKOS placement to bilateral PA on 2017/02/10 Discharge on 2017/02/24 15
Final Diagnosis Acute submassive pulmonary embolism at bilateral superior and inferior lobar arteries, status post thrombolysis via EKOS on 2017/02/10 Impending hypoxic respiratory failure, pulmonary embolism relarted 16

2 nd Time ER (Returned Visit on Next Day) 24
陳文鍾教授現場指導 ST elevation at V1-V5 Anteroseptal MI 在初次來診的 EKG 無法診斷出 MI, 故在兩次 cardiac enzyme 追蹤正常後, 給予衛教並回 CV 門診是適當的做法 25
2 nd Time ER Follow-up EKG 4 Hours Later 26
27
Subsequent Course Consult CV Echocardiogram RWMA in LAD territory Primary PCI LM: Patent LAD: proximal total occulsion LCX: proximal stenosis 80% RCA middle diffuse stenosis up to 80%, distal 90% POBAS with DES*1 to LAD 28

34
陳文鍾教授現場指導 Sinus rhythm RBBB RSR 的第一個 R wave 消失, 要想到 anterior wall MI 有 Q wave 即可代表 MI Q wave over V1-V4, II, III, avf 35
36

Patient. 177 41
Patient Data Age: 87 Sex: Male Chief complaint Shortness of breath, bradycardia noted at triage 42

45
EKG Interpretation Atrial fibrillation, with slow ventricular rate and frequent VPC Complete AV block Inferior wall MI ST elevation at III ST depression at V2-V6 Peak T wave 46
Previous EKG (1 Year Before) 47
EKG, 1 Minute Later 48
陳文鍾教授現場指導 Idioventricular rhythm 給予 Doputamine/dopamine/epinephrine 會降低 VT/VF 的 threshhold 因此此病人重要的是要盡早進導管室 在 AMI with bradycardia 的病人, TPM 應優先於 dopamine 49
Immediate Management Atropine 1mg, twice Poor response BP decreased to 63/46mmHg Dopamine premix 50
EKG, 9 Minutes Later 51
陳文鍾教授現場指導 此心律不需要用 amiodarone control 因為此 AIVR 是因為給予 dopamine 降低 VT/VF threshold 的 effect 所引起, 不需要給予 amiodarone 應迅速進導管室, 做導管的同時一併放 TPM 控制心律 另外 97 下的 VT 也不一定需要治療, 在 cardiac output 裡也只少了 atrial kicking, 故不一定需要把它打下來 若要在急診室控制心律, TCP 是較好的選擇 52
EKG, 2 Minutes Later 53
