2024年4月29日 · Journey to the heart of our being with the cardiovascular system study guide. Aspiring nurses, chart the pulsating rivers of life as you discover the anatomy and dynamics of the body's powerful pump and intricate vessel networks.

2018年1月29日 · The heart is a complex organ that pumps blood through the body with an intricate system of muscle layers, chambers, valves and nodes. It has its own circulation system and receives electric impulses that make it contract and relax, which triggers a sequence of events forming the cardiac cycle.

In cardiology, the P wave on an electrocardiogram (ECG) represents atrial depolarization, which results in atrial contraction, or atrial systole. The P wave is a summation wave generated by the depolarization front as it transits the atria.

2024年11月1日 · P-pulmonale ECG findings of a P-pulmonale pattern: Primary definition: [1] Tall, peaked P-waves in Lead II (>2.5 mm). [2] Sinus rhythm (not ectopic P-waves). The P-wave axis is generally >70 degrees (negative P-wave in aVL). Large P-waves sometimes cause diffuse ST depression (due to atrial repolarization). causes of P-pulmonale pattern:

2024年7月18日 · Paroxysmal atrial tachycardia (PAT) is a type of arrhythmia, or abnormal heartbeat. Paroxysmal means the episode of arrhythmia begins and ends abruptly. Atrial means the abnormal heart rhythm...

The P wave is the first deflection of the cardiac cycle seen on an EKG. It represents the electrical activity associated with atrial depolarization. The normal P wave is a low amplitude, vertical, rounded wave, resembling a gentle hill, which is continued immediately from the QRS complex.

However, there are numerous heart conditions that can affect its function and increase the risk of heart disease. From Atrial Fibrillation to Ventricular Septal Defect, it’s essential to understand the various heart conditions and their symptoms to maintain good heart health.
