What is V4R ECG?
The most useful lead is V4R, which is obtained by placing the V4 electrode in the 5th right intercostal space in the mid-clavicular line. ST elevation in V4R has a sensitivity of 88%, specificity of 78% and diagnostic accuracy of 83% in the diagnosis of RV MI.
Why would you do a right-sided ECG?
When the patient is suffering acute inferior STEMI a right-sided 12-lead ECG can help to identify right ventricular infarction. Be careful with nitroglycerin in the setting of right ventricular infarction. STEMI patients should be monitored continuously with defibrillation pads in place.
Where does the V4R electrode go?
The most useful lead is V4R, which is obtained by placing the V4 electrode in the 5th right intercostal space in the mid-clavicular line.
How is right ventricular infarction treated?
Fluid infusion is the mainstay of treatment for patients with RVI. In the case of an inferior MI with right ventricular involvement, the administration of nitroglycerin and morphine could cause an abrupt drop in blood pressure.
How common is a right-sided MI?
Acute myocardial infarction (MI) involving only the right ventricle is an uncommon event. More often, right ventricular MI (RVMI) is associated with acute ST-elevation MI of the inferior wall of the left ventricle and occurs in 30 to 50 percent of such cases [1-6].
What should I look for in a right sided ECG?
Run the right-sided EKG just as you would a left-sided EKG, and look for ST elevation in V2R-V6R. ST segment elevation in V4R is considered to be diagnostic for right ventricular infarction; however, any ST elevation in the right V-leads 3 through 6 should signal suspicion for a right-sided MI.
How do you identify Brugada?
The main test for Brugada syndrome is as an electrocardiogram (ECG). It checks the heart’s electrical activity and is usually done in hospital. During an ECG, small sensors are attached to your arms, legs and chest.
How is Brugada diagnosis?
To diagnose Brugada syndrome, a health care provider will perform a physical exam and listen to the heart with a stethoscope. Tests are done to check the heartbeat and diagnose or confirm Brugada syndrome.
Where is V4 placed on a child?
left medioclavicular line
Placement of chest electrodes (precordial leads) in children V4: placed on the left medioclavicular line between rib 5 and 6. V5: placed on the anterior axillary line, on level with V4.
