What is abnormal ECG graph?
An abnormal ECG can mean many things. Sometimes an ECG abnormality is a normal variation of a heart’s rhythm, which does not affect your health. Other times, an abnormal ECG can signal a medical emergency, such as a myocardial infarction /heart attack or a dangerous arrhythmia.
What are the most common ECG abnormalities?
Individual abnormalities: The 10 most common morphological abnormalities were sinus bradycardia (7.8%), right axis deviation (3.3%), non specific T wave changes (2.5%), intraventricular conduction delay (IVCD) (2.3%), prolonged QT (2.3%), A-V block first degree (2.2%), ectopic atrial rhythm (2.1%), short PR interval ( …
Why does my ECG look weird?
If your electrolytes are imbalanced, you may have an abnormal EKG reading. Heart attack or ischemia: During a heart attack, blood flow in the heart is affected and heart tissue can begin to lose oxygen and die. This tissue will not conduct electricity as well, which can cause an abnormal EKG.
How do you read graph paper on ECG?
How to read ECG paper
- Each small square represents 0.04 seconds.
- Each large square represents 0.2 seconds.
- 5 large squares = 1 second.
- 300 large squares = 1 minute.
What does sinus tachycardia look like on ECG?
Sinus tachycardia is recognized on an ECG with a normal upright P wave in lead II preceding every QRS complex. This indicates that the pacemaker is coming from the sinus node and not elsewhere in the atria, with an atrial rate of greater than 100 beats per minute.
What is a good EKG look like?
A “normal” EKG is one that shows what is known as sinus rhythm. Sinus rhythm may look like a lot of little bumps, but each relays an important action in the heart.
What does atrial flutter look like on ECG?
Atrial flutter produces a sawtooth pattern with tracings of P waves on the ECG, and AFib produces irregular QRS waves without discernible P waves.
What do PVCs look like on ECG?
This is visible on the ECG as an inverted P wave (“retrograde P wave“), usually occurring after the QRS complex. PVCs are said to be “frequent” if there are more than 5 PVCs per minute on the routine ECG, or more than 10-30 per hour during ambulatory monitoring.
Why is my EKG abnormal?
An abnormal ECG may be caused by a variety of factors, including an arrhythmia, or a faster or slower than normal heartbeat. Other causes may include a defect in the heart muscle, heart failure, and coronary artery disease.
What does an abnormal ECG reading mean?
Abnormality in ECG report generally means that the electrical system of your heart is not working properly. Abnormal ECG results may indicate heart block, Tachycardia, Bradycardia, Premature atrial contraction, heart attack and many other heart conditions.
What is a bad EKG?
An abnormal EKG can mean many things. Sometimes an EKG abnormality is a normal variation of a heart’s rhythm, which does not affect your health. Other times, an abnormal EKG can signal a medical emergency, such as a myocardial infarction (heart attack) or a dangerous arrhythmia.
What are normal ECG results?
Normal ECG. A normal ECG is illustrated above. Note that the heart is beating in a regular sinus rhythm between 60 – 100 beats per minute (specifically 82 bpm). All the important intervals on this recording are within normal ranges.
