Venous pCO2 = 47 (normal = 47), which corresponds to an arterial pCO2 of about 40 mmHg. Venous pH = 7.58 (normal = 7.33), corresponds to an arterial pH of 7.65 (very alkalemic) This was done and showed very poor LVF and no WMA.Įlectrolytes and Venous Gas results returned:Ĭhloride = 68 mEq/L (this indicates metabolic alkalosis)Īnion Gap = 3 mEq/L (so there is no serious metabolic acidosis) I recommended a bedside echo and further eval. I said that this is very unlikely to be ischemia because of:ģ) relative clinical stability in a patient with a baseline EF of 10% The physicians were worried about this and showed it to me. Voltage was high then too, but ST segments were not. The highest ST/S ratio is about 10% (normal).Ītrial fib. But there are also very deep S-waves in V3-V5 and a very tall R-wave in V6. There is a large amount of ST elevation in V3-V5, and ST depression in V6. The QRS = 134 ms, so it is an IVCD (intraventricular conduction delay), but is not LBBB because of Q-waves in I and aVL. The PR interval is 360 ms (the computer read it as 227 ms). The P-wave in V1 has a huge negative component, diagnostic of left atrial enlargement. BP was 87/52, pulse 90, saturations 100%, and respirations 14.

This article has been co-published in the European Heart Journal and the Journal of the American College of Cardiology. This statement represents an international consensus for ECG interpretation in athletes and provides expert opinion-based recommendations linking specific ECG abnormalities and the secondary evaluation for conditions associated with SCD. The objective of the meeting was to define and revise ECG interpretation standards based on new and emerging research and to develop a clear guide to the proper evaluation of ECG abnormalities in athletes.
#IVCD ECG IMAGES UPDATE#
On February 26-27, 2015, an international group of experts in sports cardiology, inherited cardiac disease, and sports medicine convened in Seattle, Washington, to update contemporary standards for ECG interpretation in athletes.
Since the original 2010 European Society of Cardiology recommendations for ECG interpretation in athletes, ECG standards have evolved quickly over the last decade pushed by a growing body of scientific data that both tests proposed criteria sets and establishes new evidence to guide refinements. A critical need exists for physician education in modern ECG interpretation that distinguishes normal physiological adaptations in athletes from distinctly abnormal findings suggestive of underlying pathology.
However, in most countries a shortage of physician expertise limits wider application of the ECG in the care of the athlete. Whether used for diagnostic or screening purposes, physicians responsible for the cardiovascular care of athletes should be knowledgeable and competent in ECG interpretation in athletes. A variety of mostly hereditary, structural, or electrical cardiac disorders are associated with SCD in young athletes, the majority of which can be identified or suggested by abnormalities on a resting 12-lead electrocardiogram (ECG). Sudden cardiac death (SCD) is the leading cause of mortality in athletes during sport.
