A criterion for sinus rhythm is that P waves and QRS complexes appear 1-to-1, thus implying that the P wave causes the QRS complex.With practice, interpreting the ECG is a matter of pattern recognition.However, the ECG can be analysed from first principles if a few simple rules and basic facts are remembered.The previous chapters reviewed the cycle of atrial and ventricular depolarization and repolarization detected by the ECG as well as the 12-lead system used to record this electrical activity.Indeed, the ECG gives the impression that repolarization starts earlier than normal in these patients.It indicates that there is a ST elevation but there is no underlying disease.

It is also used to detect myocardial injury, ischemia, and the presence of prior infarction.While it is a relatively simple test to perform, the interpretation of the ECG tracing requires significant amounts of training.This book takes a logical and systematic approach to ECG interpretation, beginning with the basics of normal variations and dealing in turn with atrial abnormalities, ventricular enlargement.An electrocardiogram — abbreviated as EKG or ECG — is a test that measures the electrical activity of the heartbeat.The electrocardiogram (ECG or EKG) is a diagnostic tool that is routinely used to assess the electrical and muscular functions of the heart.

But I found a few links for you that show ECGs and a little explanation about what the waves mean.This is a skill that is developed through practice and variety.
Characteristics of the Normal ECG It is important to remember that there is a wide range of normal variability in the 12 lead ECG.Probable left atrial It indicates that there is a ST elevation but there is no underlying disease.
Normal Tracing - ECGpediaNormal sinus rhythm produces the prototypical pattern of P wave, QRS complex, and T wave.

This wave causes the muscle to squeeze and pump blood from the heart.Generally, deviation from normal sinus rhythm is considered a cardiac arrhythmia.
Electrocardiogram (ECG or EKG) - American Heart AssociationBACKGROUND: The male and female patterns of early ventricular repolarization in normal ECGs differ from each other.
Brugada Syndrome vs Pattern: What You Should KnowNormal EKG pattern consists of 5 waves, two segments and two intervals.
These tracings, the EKG waveform, have key features which indicate sinus rhythm or abnormalities (arrhythmias).Interestingly, fever has also been shown to unmask the type 1 ECG pattern and may precipitate ventricular arrhythmias.
Normal 12-Lead | ECG Guru - Instructor ResourcesEach normal cardiac electrical cycle starts with the generation of a regular depolarisation in a specialised area of cardiac tissue in the right atrial wall, known as the sinoatrial (SA) node.A diagnostic ECG may be produced in these patients by administration of a sodium-channel blocking agent, typically a class I antiarrhythmic such as flecainide or procainamide.
An electrocardiogram (EKG or ECG) is a test that records the electrical activity of your heart.
