EKGs captures a tracing of cardiac electrical impulse as it moves from the atrium to the ventricles. These electrical impulses cause the heart to contract and pump blood. EKGs are interpreted by medical professionals to understand the following:. This introductory course reviews the main features of electrocardiogram strips. A method for analyzing an electrocardiogram is presented.

This method includes assessment of rhythm, calculating heart rate, observing P-wave forms, measurement of wave intervals and segments and the evaluation of other relevant waves. In addition, our drills allow students to practice electrocardiogram identification. Users are asked to identify the arrhythmia category. Immediate feedback is available after answering a multiple choice question.

Our quiz presents twenty tracings for interpretation. A graded quiz provides detailed feedback. Quiz ekg tracings are randomly selected from our database of tracing, so the quiz can be repeated many times.

For each type there are patient tracings and simulated electrocardiograms. We also provide an annotated tracing with a summary of the key features and values. Interactive digital calipers can be used for measuring key features on each tracing.

Our Monitor Quiz is similar to the standard Quiz, but with a twist. Instead of static tracings, the ECGs are presented using a simulated patient monitor. After the twenty tracings are evaluated, we present a graded report along with static images of each tracing. Your score is compared to a mean score for all recent website visitors. Don't worry, your score is kept private. The EKG rhythm will appear regular. The heart rate is bpm, which is faster than a ventricular rhythm but slower than ventricular tachycardia.

The P wave is absent and PR interval is not measurable. The EKG rhythm will appear regular with heart rate that is normal bpm. The P wave is present before, during hidden or after QRS.

EKG/ECG Interpretation (Basic) : Easy and Simple!

If visible it is inverted. The PR interval is not measurable. The QRS complex will typically be normal 0. Cardiac electrical activity is absent. No EKG rhythm can be observed. The P wave and QRS complex are not visible. Confirm using multiple leads. The EKG rhythm will appear irregular. Heart rate is very fast: over bpm for atrial, but ventricular rate may be slow, normal or fast. The P wave features are absent - erratic waves are present. The PR interval is absent.

The QRS complex will typically be normal but may be widened if there are conduction delays. The atrial heart rate is rapid bpmbut ventricular rate is often slower. EKG rhythm will appear more regular thank atrial fibrillar.Transcript: Endocardial transvenous approach Epicardial surgical approach The Pacemaker Step1: use index card and place above 2 consecutive paced beats, marking automatic interval Step 2: Start at left side and analyze each pacer spike Step 3: Select the pacing spike to analyze Step 4: Observe relationship Implantation How pacemakers keep hearts beating Follow up Failure to Fire Background Implanted Pacemakers A device that sends small electrical impulses to the heart muscle to maintain a suitable heart rate or to stimulate the ventricles of the heart.

Next, the electrical impulse travels through the AV node.

The AV node slows the signal before it enters the ventricle. From the AV node, the electrical impulse travels through the bundle of His and the Purkinje network. The impulse travels into the muscular walls of the ventricles, causing them to contract.

It represents ventricular repolarisation. Should be upright in all leads except aVR and V1 Things to consider: In left atrial enlargement, left atrial depolarization lasts longer than normal but its amplitude remains unchanged. It is often a precursor to atrial fibrillation. The ECG wave P wave QRS waves T wave Sinus Question time In right atrial enlargement, right atrial depolarisation lasts longer than normal and its waveform extends to the end of left atrial depolarisation.

Although the amplitude of the right atrial depolarisation current remains unchanged, its peak now falls on top of that of the left atrial depolarisation wave.A comprehensive collection of clinical examination OSCE guides that include step-by-step images of key steps, video demonstrations and PDF mark schemes.

If a patient has a regular heart rhythm their heart rate can be calculated using the following method:. As a result, you need to apply a different method such as:. Mark out several consecutive R-R intervals on a piece of paper, then move them along the rhythm strip to check if the subsequent intervals are similar.

If you are suspicious that there is some atrioventricular block AV blockmap out the atrial rate and the ventricular rhythm separately i. As you move along the rhythm strip, you can then see if the PR interval changesif QRS complexes are missing or if there is complete dissociation between the two. If P waves are absent and there is an irregular rhythm it may suggest a diagnosis of atrial fibrillation. To help remember these degrees of AV block, it is useful to remember the anatomical location of the block in the conducting system:.

When assessing a QRS complex, you need to pay attention to the following characteristics:. Clinical Examination. Anatomy of the Uterus. Prescribing in Primary Care. Interpreting a Coagulation Screen.

They indicate situations in which intervention is required. This means delivery or alleviation of a cause of fetal distress such as over-stimulation or maternal hypotension. During the second stage of labour with active pushing, immediate delivery is recommended. If there is an abnormal CTG and a normal ST during the second stage of labour, you can wait 90 minutes before intervention.
