【正文】 duction system is still excitable. Then, the sinus impulses will conduct to the ventricles through the conduction system without the atria being depolarized – thus referred to as sinoventricular rhythm. Which electrolyte problem is this tracing suggestive of? Anteroseptal Infarct or Pseudoinfarction Pattern From Hyperkalemia? ? Which of the following conditions is responsible for the ST elevation in leads V12? Choose from the list below. ? A) Acute anteroseptal infarct B) Pseudoinfarction pattern from hyperkalemia Pseudoinfarction pattern from hyperkalemia ? Pseudoinfarction pattern from hyperkalemia is tachycardia at a rate of 130 beats per minute is present. The ST segment is elevated in V1 and V2, raising the possibility of acute anteroseptal myocardial infarction. However, the T wave is very tall, narrow, pointed, and tented。 Ⅰ 類藥臨床試驗(yàn) 綜合以上 Ⅰ 類試驗(yàn) 59項(xiàng) ? 治療組死亡率 % ? 對照組的 % Ｐ＝ 結(jié)論： I類抗心律失常藥物 增加死亡率 II類 β 阻滯劑臨床試驗(yàn) 共 55項(xiàng)： 53268例 ?治療組 26973 ?死亡率 % ?對照組 26295例 ?死亡率 % Ｐ＜ 結(jié)論：不管心梗后早期干預(yù)或晚期干預(yù)，均 顯著降低死亡率 Ⅲ 類 ——胺碘酮的臨床試驗(yàn) 總共有 9項(xiàng)， 1557例 （其中 5項(xiàng)在 AMI后一個(gè)月內(nèi)進(jìn)行） ? 治療組 778例 ? 死亡率 % ? 對照組 779例 ? 死亡率 13% Ｐ＝ 綜合全部資料治療組死亡率降低 29%。 and the QRS is wide, measuring 140 msec. ? These findings are characteristic of hyperkalemia. It is well known that hyperkalemia can cause STsegment elevation (pseudoinfarction pattern or dialyzable current of injury). ? This tracing is from a patient with a serum potassium level of mEq/L during diabetic ketoacidosis, who also is in renal failure and taking an angiotensinconverting enzyme
