An abnormal ekg strip will not follow the traditional p wave qrs wave and t wave order. Multiple electrical events called p q r s t and u may be observed on an ekg strip.

Abnormal ekg rhythms are called arrhythmias although sometimes the term dysrhythmias may be used.

Ekg rhythm strip interpretation. It is preferred by other doctors as ekg to lessen the confusion between ecg and eeg which stands for electroencephalogram. Arrhythmia is an abnormally slow or fast heart rate or an irregular cardiac rhythm. Defined as an enhanced ectopic ventricular rhythm with at least 3 consecutive ventricular beats which is faster than normal intrinsic ventricular escape rhythm 40 bpm but slower than ventricular tachycardia.

Abnormal rhythms are called arrhythmia or sometimes dysrhythmia. Arrhythmia is an irregular cardiac rhythm or an abnormally fast or slow heart beat. Ekg can include various waveform components which are can be interpreted to understand if the ekg is a sinus rhythm or abnormal.

You will need to look at the whole strip to check for an irregular heartbeat. What does an abnormal ekg strip look like. Interpreting ekg rhythm strips step 1 heart rate methods to determine heart rate the 6 second method denotes a 6 second interval on ekg strip strip is marked by 3 or 6 second tick marks on the top or bottom of the graph paper count the number of qrs complexes occurring within the 6 second interval.

This is usually a 10 second recording from lead ii. During a single heart beat several electrical events occur. How many seconds is an ekg strip.

One of the most useful and commonly used diagnostic tools is electrocardiography ekg which measures the heart s electrical activity as waveforms. Look at the peaks on the printout. Aivr results when the rate of an ectopic ventricular pacemaker exceeds that of the sinus node often associated with increased vagal tone and decreased sympathetic tone.

The first thing to look at is whether or not the qrs rhythm is regular or irregular. Study of a patient s cardiac rhythms using an ekg may indicate normal or abnormal conditions. Most ekg strips are 6 seconds the graph paper has a marking on the top or bottom to indicate every 3 seconds.

This is a pattern called normal sinus rhythm and it s the basic ekg of a healthy heart. You can also count the large boxes 30 large boxes equal 6 seconds most 12 lead ekgs are 10 seconds long. Many people s ekg may vary slightly from this baseline though while still being completely healthy.

These ekg tracings have important features which can be analyzed to reveal a normal or an abnormal rhythm a dysrhythmia. Ekg waveforms are displayed on monitors or paper. Electrocardiogram ecg ekg is a tool used to visualize the electricity that flows through the heart.

An ekg uses electrodes attached to the skin to detect electric current moving through the heart. This can be done by inspecting the rhythm strip and looking at the r r interval. The best way to assess the ecg rhythm is by inspecting the rhythm strip.

Ekg rhythms are used to characterize certain heart conditions. Use this ekg interpretation cheat sheet that summarizes all heart arrhythmias in an easy to understand fashion. It is used to check for the rhythm of your heart that could indicate whether it is normal or abnormal.
