Inferior leads Leads II, III and aVF Look at electrical activity from the vantage point of the inferior surface diaphragmatic surface of heart Lateral leads I, aVL, V5 and V6 Look at the electrical activity from the vantage point of the lateral wall of left ventricle Septal leads V1 and V2 Look at electrical activity from the vantage point of the septal surface of the heart interventricular septum Anterior leads V3 and V4 Look at electrical activity from the vantage point of the anterior wall of the right and left ventricles Sternocostal surface of heart In addition, any two precordial leads next to one another are considered to be contiguous.
Electricity, drugs, lytics, cath lab? Written by Pendell Meyers with edits by Steve Smith A male in his 60s presented with off and on shortness of breath and chest pressure over the past few days. He was hypertensive and tachycardic, with mildly increased work of breathing.
Here is his initial ECG: What do you think? What will you do for this patient? How many problems does he have? Therefore this patient is either in some form of SVT or atrial flutter.
Atrial flutter, when regular, must be conducting at 1: Atrial flutter in the absence of modifying medications is generally from bpm. Furthermore, most old adult AV nodes cannot conduct at bpm. This is far too fast for flutter.
The most common case of atrial flutter results in a ventricular rate of approximately bpm, due to the average size of the atria and the normal rate of atrial conduction resulting in an atrial rate of approximately bpmcombined with the typical capacity of the AV node to conduct usually 2: So we asked the patient if he had any new medications recently.
He said, "I just started taking flecainide last week. This new information makes the diagnosis of atrial flutter far more likely: Back to the interpretation of the ECG: Does the rhythm matter to you in this case?
The rhythm does matter! For many reasons, including these: In some cases the ischemia can be seen "through" the flutter waves, whereas in other cases the arrhythmia must be terminated before the ischemia can be clearly distinguished.
First, there can simply be diffuse ST depressions which obligates reciprocal STE in aVR associated with tachycardia which are not indicative of ischemia. Second, the increased demand created by extreme tachycardia may exceed the ability of the coronary arteries to supply sufficient blood due to preexisting three vessel or left main disease, with or without ACS.
So you do care what the rhythm is, and you should be wondering: If I fix the rhythm will the ST changes resolve?
Is he even stable enough to attempt changing his rhythm? Is he unstable enough to warrant cardioversion? Do ischemic changes on ECG mean unequivocally that the rhythm is "unstable" and therefore mandate electrical cardioversion?ECG filters can have a substantial effect on the test results in IEC , IEC and IEC In some clauses the standard indicates which filter(s) to use, but in most cases, the filter setting is not specified.
