What else can I help you with?
By what measure does sentinel lymph node biopsy have a significantly lower rate of complications than axillary lymph node dissection?
One study found that only 2.6% of patients who had SLNB developed lymphedema, compared to 27% of patients who had ALND.
What is the survival rate of stage2a breast cancer?
For stage I (early/lymph node negative), which comprises 40-45% of total cases, the five-year survival is 85-95%.
How many women develop lymphedema after axillary lymph node removal during a mastectomy?
Approximately 10% to 20% of patients develop lymphedema after axillary lymph node removal. however if you get radiation your rate goes up to 50% and good chance of developing lymphedema
What conducting cells set heart rate?
Sinoatrial Node (SA node)
Intrinsic rate of AV node?
The intrinsic rate of the AV node, also known as the inherent pacemaker rate, is the rate at which the AV node generates electrical impulses when not influenced by outside factors. It is typically around 40-60 beats per minute and serves as a backup pacemaker if the SA node fails to function properly. The AV node's intrinsic rate helps to regulate the heart rate and maintain cardiac function.
What is the firing rate of AV node?
50
What controls rate of heartbeat?
the SA node
The rate and pace of the heart is set by what?
The rate and pace of the heart are set by the SA node. There are backup systems in place if the SA node fails to do its job.
If there is a complete block between the SA node and the AV node how would the ECG be affected?
The rate of P waves will be faster than the rate of QRS complexes.
Which side of the Titanic had the most survival rate?
Portside had the most survival rate
What is the normal rate of the SA node?
60-100
What is a atrioventrical node?
The atrioventricular node is a part of electrical control system of the heart that co-ordinates heart rate.
