This WPW pattern doesn’t typically cause any symptoms and it’s relatively benign. In some cases, however, this pattern can facilitate certain arrhythmias, or basically make certain arrhythmias more severe and potentially even cause sudden cardiac death, in which case it would be called Wolff-Parkinson-White syndrome.
The diagnosis of WPW occurs with a combination of palpitations and when an electrocardiogram (ECG) show a short PR interval and a delta wave. [3] It is a type of pre-excitation syndrome. [3] WPW syndrome may be monitored or treated with either medications or an ablation (destroying the tissues) such as with radiofrequency catheter ablation. [4]
12 lead electrocardiogram of an individual with Wolff–Parkinson–White syndrome exhibiting 'slurred upstrokes' or 'delta waves' before the QRS complexes. An episode of SVT may present with palpitations, dizziness, shortness of breath, or losing consciousness (fainting). The electrocardiogram (ECG) would appear as
People with no symptoms, normal lab tests, and normal EKG results can usually leave the emergency department safely. They should follow up with their primary care doctor or a cardiologist. [ 1 ] However, patients with palpitations linked to fainting ( syncope ), uncontrolled arrhythmias, poor blood flow ( hemodynamic issues), or chest pain ...
Gamma waves are seen when a person is highly focused on a task or using all their concentration. Theta waves occur during the period of a person being awake, and they continue to transition into Stage 1 of sleep and in stage 2. Delta waves are seen in stages 3 and 4 of sleep when a person is in their deepest of sleep. [19]
Abnormal heart rhythms can also result, and ECG findings of a short QT interval [26] suggest hypercalcaemia. Significant hypercalcaemia can cause ECG changes mimicking an acute myocardial infarction. [27] Hypercalcaemia has also been known to cause an ECG finding mimicking hypothermia, known as an Osborn wave. [28]
[1] [2] Patients observe these symptoms and seek medical advice from healthcare professionals. Because most people are not diagnostically trained or knowledgeable, they typically describe their symptoms in layman's terms, rather than using specific medical terminology. This list is not exhaustive.
Targeted temperature management (TTM), previously known as therapeutic hypothermia or protective hypothermia, is an active treatment that tries to achieve and maintain a specific body temperature in a person for a specific duration of time in an effort to improve health outcomes during recovery after a period of stopped blood flow to the brain.
