⩥ When do ST-segment and T-wave changes occur?
Answer: with myocardial ischemia, prior to permanent cell damage.
⩥ What are ST-segment and T-wave elevation indicative of?
Answer: fetus at risk of developing hypoxia but still capable of
responding against hypoxemia.
⩥ What are ST-segment and T-wave depression indicative of?
Answer: has been associated with the inability of the fetal heart to
further respond to hypoxia, indicating that the fetus either had no time to
respond or has exhausted compensatory mechanisms.
⩥ When are fetal ST changes clinically relevant?
Answer: when they coincide with category 2 tracings
, ⩥ How do you differentiate an irregular heart rate from possible artifact
or electronic interference?
Answer: - auscultation
- ultrasound
- echocardiogram
- ecg
⩥ What is an arrhythmia?
Answer: - the sporadic, irregular beats typical of the frequent fetal
events heard or recorded on the tracing
- When there is a disturbance in the heart cell's ability to form and
discharge an impulse independently (automaticity & excitability),
cardiac rhythm may become tachycardic, bradycardic, or irregular with
ectopic beats or premature rhythms such as premature atrial
contractions.
⩥ How are arrythmias categorized?
Answer: - based upon the anatomical site of variant impulse formation,
conduction, or a combination of both
⩥ What is the prognosis regarding arryhtmias?
Answer: - Most are benign and require no intervention
- Most will convert to a normal sinus rhythm after birth
