does vf have a pulse?

A heart monitor that will read the electrical impulses that make your heart beat will show that your heart is beating erratically or not at all. Pulse check. In ventricular fibrillation, there will be no pulse.

There are no visible P waves. There is a sawtooth baseline in V1 with flutter waves visible at 300 bpm. Elsewhere, flutter waves are concealed in the T waves and QRS complexes. The heart rate of 150 bpm makes this flutter with a 2:1 block.

The heart rate during SVT is usually between 120-240 beats-per-minute. SVT can last for a few seconds or may last for several days.
488421
In patients with atrial fibrillation (AF), the ventricular rate is controlled by the conduction properties of the atrioventricular (AV) node. In the typical patient with untreated AF, the ventricular rate can reach 150 beats/min or higher.

Most innocent murmurs disappear when a child reaches adulthood, but some adults still have them. When a child's heart rate changes, such as during exercise, excitement or fear, the innocent murmur may become louder or softer.

A pulse wave or pulse train is a kind of non-sinusoidal waveform that includes square waves (duty cycle of 50%) and similarly periodic but asymmetrical waves (duty cycles other than 50%). ... The pulse wave is also known as the rectangular wave, the periodic version of the rectangular function.

In some cases of AFib, the fibrillation of the atria causes the ventricles, or lower chambers of the heart, to beat too fast. This is called a rapid ventricular rate or response (RVR). If you have AFib with RVR you'll experience symptoms, typically a rapid or fluttering heartbeat.

The first time you go to a power flow class, your heart rate might inch up to 175 beats per minute, but if you go to that same class three times a week for six months, your heart rate might rise to only 160 beats per minute. That's a good thing.

When you need a defibrillator. You need an ICD if you have ventricular fibrillation (VF). That's when the heart's lower chambers don't contract hard enough to pump blood throughout the body, triggering cardiac arrest. You also need one if you've already suffered cardiac arrest, from VF or another cause.

Deviations from this normal range reflect either hypovolemia (i.e., mean venous pressure less than 5 cm H2O) or impaired cardiac filling (i.e., mean venous pressure greater than 9 cm H2O). The normal jugular venous pulse contains three positive waves.

The type of fast heart rate that occurs is called supraventricular tachycardia (SVT). So, WPW is a sub-group of patients with SVT. Pre-excitation is a finding on the resting electrocardiogram (ECG) that is specific to WPW.

The initial rhythm may be ventricular fibrillation (VF), pulseless ventricular tachycardia (VT), asystole, or pulseless electrical activity (PEA).
129865
Supraventricular tachycardia (SVT) is a faster than normal heart rate above the ventricles, which can cause the atria to beat between 100 - 300 beats per minute. Atrial fibrillation (afib) is when the atria of the heart flutter or shiver rather than fully contract.

The carotid is the preferred pulse point used during resuscitation of adults. In the lower extremities, the commonly evaluated pulses are the femoral, posterior tibial, dorsalis pedis, and sometimes the popliteal.
1244447
If the pulse is fast and irregular, then the person is more likely to have AFib. Although some people have no symptoms and cannot feel the arrhythmias, common clinical symptoms of both arrhythmias are: Palpitations (person feels their heart beating or pounding) Fatigue.

High Frequency Percussive Ventilation HFPV is delivered via the volumeric diffusive ventilator (VDR). ... High-pressure gas drives the Phasitron to deliver small tidal volumes at a high frequency (200 to 900 beats per minute), superimposed on the inspiratory and expiratory airway pressures of PCV.
158054
Pulseless ventricular tachycardia and ventricular fibrillation are treated with unsynchronized shocks, also referred to as defibrillation. ... EKG synchronization is not possible with VF, since it is a chaotic, disorganized rhythm.
