Depending on the cause of triggered arrhythmias differ should be routine examination electrolyte and acid-base balance; check the thyroid function in renal function; check the erythrocyte sedimentation rate of anti-"O" immune function and myocardial enzymes, etc.
1. Electrocardiogram
(1) ECG: It is the most important means of diagnosis of the clinical arrhythmia adopted a 12-lead ECG from the heart arrhythmia in three-dimensional structure to determine the nature and location of 12-lead ECG, however, due to the short recording time is not easy to describe charged to the short-term Therefore, the clinical arrhythmia graphics using P-wave is often a clear lead (Ⅱ Ⅲ aVF, and V1 lead) recorded easy to describe a long time to catch attention of P and QRS wave arrhythmia patterns P-QRS relationship PPPR and RR interval to determine the basic rhythm was sinus atrio-ventricular ectopic activity independent of, or to find out when the P wave and QRS wave group the origin of (select Ⅱ aVFaVRV1 and V5V6-lead) P-wave was not obvious may try to increase voltage or speed up the paper for P-wave velocity than the obvious lead of the long record (2) esophageal ECG: You can clearly describe P-wave recorded on the 12-lead ECG P-wave records of patients who do not know the easy availability of P-wave information can help correct diagnosis
(3) electrocardiographic monitoring: In order to overcome a short time Electrocardiography arrhythmia difficult to capture the shortcomings of the people using the method of diagnosis of ECG arrhythmia monitoring
① Cable bedside electrocardiographic monitoring: for critically ill patients
② wireless ECG monitoring: easy to capture activity in patients with arrhythmia after
③ dynamic ECG: Holter electrocardiogram, also known as a continuous record of 24h or more of the electrocardiogram and its emergence can not be solved solely ordinary ECG diagnosis of arrhythmias issue through a 24-hour continuous ECG recording may be recorded in the onset of arrhythmia in the autonomic nervous system on the spontaneous the impact of arrhythmia and arrhythmia in the relationship between the symptoms and to assess the treatment effect is difficult, however, are not always recorded in the onset of arrhythmia
④ Telephone ECG: The ECG channels through the phone transferred to the hospital or patient monitoring center will help to understand the working and living conditions when the arrhythmia
(4) His body surface electrogram: ECG using methods such as filtering, and stacking of the His electrogram recorded to assist in the analysis of atrial and ventricular electrogram His bundle of mutual relations and the order of supporting the diagnosis of complex arrhythmias
(5) The surface ECG mapping: The scores of the individual sheet electrodes recorded simultaneously in different parts of the heart to facilitate analysis of ECG arrhythmias, as well as the origin point of order and the speed of conduction abnormalities in particular, the diagnostic value of abnormal channels (6) signal averaged ECG (signal averaged ECG) also known as high-resolution ECG (high resolution body surface ECG) may be recorded in the superficial signs ventricular regional myocardial conduction delay due to delayed depolarization of the ventricular late potential in the presence of ventricular late potentials for the reentry and thus provide a favorable environment to form the basis of ventricular late potentials recorded in patients whose ventricular tachycardia ventricular fibrillation and sudden death increased the risk of the corresponding
2. Cardiac electrophysiology study, the clinical use of cardiac electrophysiology catheter within the heart of all parts of ECG records, and pulsed electrical stimulation of different parts of the myocardial tissue of a cardiac arrhythmia research methods are invasive electrophysiological examination is aimed at better understanding of the normal and abnormal electrical activity of cardiac arrhythmias make a diagnosis of complex arrhythmias, and to determine the degree of risk and prognosis, as well as assist in the selection of treatment methods and to develop treatment programs this approach can be used to reflect the origin of cardiac electrical activity and excitement of the conduction sequence For the clinical diagnosis difficult or otherwise unable to detect arrhythmia has a very important diagnostic and differential diagnostic value of
3. Exercise test may be intermittent episodes of arrhythmia during seizures induced by intermittent arrhythmia arrhythmia and thus contribute to the diagnosis of anti-arrhythmic drugs (in particular, caused by ventricular conduction slowing down the drug) treatment after exercise test-induced ventricular heart moving too fast might be the performance of the role of drug-induced arrhythmia
4. Other tests ECG spectral analysis of ventricular late potential ventricular rate variability analysis of exercise electrocardiography and tilt test have contributed to complex or addition, certain specific arrhythmia diagnosis by echocardiography and cardiac MRI and other X-ECTCT for organic and non-organic diagnosis of arrhythmia can not be underestimated the value of
