What does undetermined rhythm mean?
Definition. An electrocardiographic finding of a cardiac rhythm whose mechanism cannot be determined from the ECG. ( CDISC) [from NCI]
What is a normal Q wave?
Normal septal q waves are characteristically narrow and of low amplitude. As a rule, septal q waves are less than 0.04 sec in duration. A Q wave is generally abnormal if its duration is 0.04 sec or more in lead I, all three inferior leads (II, III, aVF), or leads V3 to V6.
What does Cannot rule out anterior infarct age undetermined mean?
If the finding on an ECG is “septal infarct, age undetermined,” it means that the patient possibly had a heart attack at an undetermined time in the past. A second test is typically taken to confirm the finding, because the results may instead be due to incorrect placement of electrodes on the chest during the exam.
How do you interpret an ECG?
Methodological ECG Interpretation The ECG must always be interpreted systematically. Failure to perform a systematic interpretation of the ECG may be detrimental. The interpretation algorithm presented below is easy to follow and it can be carried out by anyone.
Is there an ECG interpretation algorithm for the ECG?
The interpretation algorithm presented below is easy to follow and it can be carried out by anyone. The reader will gradually notice that ECG interpretation is markedly facilitated by using an algorithm, as it minimizes the risk of missing important abnormalities and also speeds up the interpretation. 1.
What is the normal p wave amplitude for ECG?
www.ecgwaves.com | Learn ECG Interpretation Online ♥ P-wave amplitude should be ≤2,5 mm (all leads). PR interval must be 0,12–0,22 s (all leads).
What is the normal T wave progression in ECG?
•♥T-wave progression should be normal in chest leads. •♥In limb leads the amplitude is highest in lead II, and in the chest leads the amplitude is highest in V2–V3. ♥Normal variants: An isolated (single) T-wave inversion is accepted in lead V1 and lead III.
