Valenti O, Di Prima FA, Renda E, Faraci M, Hyseni E, De Domenico R, Monte S, Giorgio E. Fetal cardiac function during the first trimester of pregnancy. Imagine what it would sound like if you had ongoing audio of your heart rate as you were starting to exercise and then cooling down. Structured intermittent auscultation is a technique that employs the systematic use of a Doppler assessment of fetal heart rate (FHR) during labor at defined timed intervals . WebFetal Heart Rate Deceleration Quiz (Early, Late, Variable) This fetal heart rate quiz will test your knowledge about fetal decelerations during labor. The fetal heart rate undergoes constant and minute adjustments in response to the fetal environment and stimuli. Cardiotocography (CTG) is a technique used to monitor the fetal heartbeat and the uterine contractions during pregnancy and labour.The machine used to perform the monitoring is called a cardiotocograph.. Fetal heart sounds was described as early as 350 years ago and approximately 200 years ago mechanical stethoscopes, such as the Pinard horn, were However, if a fetal heartbeat is off by a week or more, it can indicate that a miscarriage is more likely. Check out a suggested systematic approach from the AAFP below! Since variable and inconsistent interpretation of fetal heart rate tracings may affect management, a systematic approach to interpreting the patterns is important. Most external monitors use a Doppler device with computerized logic to interpret and count the Doppler signals. With early decelerations, the point when the fetal heart rate is at its slowest (called the nadir) and the peak of the uterine contraction happen at the same time. The physiology behind late deceleration is uteroplacental insufficiency.16,17 Transient late deceleration patterns may be seen with maternal hypotension or uterine hyperstimulation. It's fastest at around 9 weeks gestation then gradually slows after the 13th week of pregnancy. A decrease in FHR of > 15 beats per minute measured from the most recently determined baseline rate. 2015 Oct;55(5):464-72. doi: 10.1111/ajo.12395. Your obstetrician reviews the fetal heart tracing at regular time intervals. Subramanian et al. Long-term variability is a somewhat slower oscillation in heart rate and has a frequency of three to 10 cycles per minute and an amplitude of 10 to 25 bpm. Periodic changes in FHR, as they relate to uterine contractions, are decelerations that are classified as recurrent if they occur with 50 percent or more of contractions in a 20-minute period, and intermittent if they occur with less than 50 percent of contractions.11 The decrease in FHR is calculated from the onset to the nadir of the deceleration. As Low As Reasonably Achievable (ALARA) Principle. Internal FHR monitoring is accom-plished with a fetal electrode, which is a spiral wire placed directly on the fetal scalp or other presenting part. There is also a slowing of the normal fetal heart rate in the last 10 weeks of pregnancy, though the normal fetal heart rate is still about twice the normal adult's resting heart rate. !e&&(e===v||"GeneratorFunction"===(e.displayName||e.name))},t.mark=function(t){return Object.setPrototypeOf?Object.setPrototypeOf(t,b):(t.__proto__=b,c(t,u,"GeneratorFunction")),t.prototype=Object.create(w),t},t.awrap=function(t){return{__await:t}},x(S.prototype),c(S.prototype,a,(function(){return this})),t.AsyncIterator=S,t.async=function(e,r,n,o,i){void 0===i&&(i=Promise);var a=new S(s(e,r,n,o),i);return t.isGeneratorFunction(r)?a:a.next().then((function(t){return t.done?t.value:a.next()}))},x(w),c(w,u,"Generator"),c(w,i,(function(){return this})),c(w,"toString",(function(){return"[object Generator]"})),t.keys=function(t){var e=Object(t),r=[];for(var n in e)r.push(n);return r.reverse(),function t(){for(;r.length;){var n=r.pop();if(n in e)return t.value=n,t.done=!1,t}return t.done=!0,t}},t.values=j,T.prototype={constructor:T,reset:function(t){if(this.prev=0,this.next=0,this.sent=this._sent=void 0,this.done=!1,this.delegate=null,this.method="next",this.arg=void 0,this.tryEntries.forEach(R),!t)for(var e in this)"t"===e.charAt(0)&&r.call(this,e)&&!isNaN(+e.slice(1))&&(this[e]=void 0)},stop:function(){this.done=!0;var t=this.tryEntries[0].completion;if("throw"===t.type)throw t.arg;return this.rval},dispatchException:function(t){if(this.done)throw t;var e=this;function n(r,n){return a.type="throw",a.arg=t,e.next=r,n&&(e.method="next",e.arg=void 0),! : qtcarbrowser|\/(20\d\d\.[-\w\.]+))/i,/m?

Nonreassuring patterns such as fetal tachycardia, bradycardia and late decelerations with good short-term variability require intervention to rule out fetal acidosis. At this point, a normal fetal heart rate is about the same as the gestational parents':80 to 85 beats per minute (bpm). ", Moderate baseline fetal heart rate variability reflects the delivery of oxygen to the fetal central nervous system. [\/ ]?([\w\. For example, fetuses with intrauterine growth restriction are unusually susceptible to the effect of hypoxemia, which tends to progress rapidly.4, A growing body of evidence suggests that, when properly interpreted, FHR assessment may be equal or superior to measurement of fetal blood pH in the prediction of both good and bad fetal outcomes.13 Fetuses with a normal pH, i.e., greater than 7.25, respond with an acceleration of the fetal heart rate following fetal scalp stimulation. To provide a systematic approach to interpreting the electronic fetal monitor tracing, the National Institute of Child Health and Human Development convened a workshop in 2008 to revise the accepted definitions for electronic fetal monitor tracing. A change in baseline FHR is said to occur when the change persists for 10 minutes or longer. Accelerations represent a sudden increase in FHR of more than 15 bpm in bandwidth amplitude. continue observing the fetal heart rate these are an expected finding a nurse manager is planning to make changes to the current scheduling system on the unit. Continuous EFM may adversely affect the labor process and maternal satisfaction by decreasing maternal mobility, physical contact with her partner, and time with the labor nurse compared with structured intermittent auscultation.7 However, continuous EFM is used routinely in North American hospitals, despite a lack of evidence of benefit.

What is the "normal" fetal heart rate? Your doctor uses special types of equipment to conduct electronic fetal monitoring. Baseline fetal heart rate variability refers to the fluctuation between fetal heartbeats. Though there are many words to describe the moment that you first hear your baby's heartbeat, most people use words like galloping to describe how the heart rate sounds. Table 7 lists signs associated with variable decelerations indicating hypoxemia4,11,26 (Figures 9 and 10).

The onset, nadir, and recovery of the deceleration usually coincide with the beginning, peak, and ending of the contraction, respectively.11 Early decelerations are nearly always benign and probably indicate head compression, which is a normal part of labor.15, Variable decelerations (Online Figure I), as the name implies, vary in terms of shape, depth, and timing in relationship to uterine contractions, but they are visually apparent, abrupt decreases in FHR.11 The decrease in FHR is at least 15 bpm and has a duration of at least 15 seconds to less than two minutes.11 Characteristics of variable decelerations include rapid descent and recovery, good baseline variability, and accelerations at the onset and at the end of the contraction (i.e., shoulders).11 When they are associated with uterine contractions, their onset, depth, and duration commonly vary with successive uterine contractions.11 Overall, variable decelerations are usually benign, and their physiologic basis is usually related to cord compression, with subsequent changes in peripheral vascular resistance or oxygenation.15 They occur especially in the second stage of labor, when cord compression is most common.15 Atypical variable decelerations may indicate fetal hypoxemia, with characteristic features that include late onset (in relation to contractions), loss of shoulders, and slow recovery.15. The FHR recordings may be interpreted as reassuring, nonreassuring or ominous, according to the pattern of the tracing.
