A new study gives insights into the complex synchronization of two cellular clocks that help regulate the human heartbeat, pointing toward new potential therapeutic mechanisms for heart rhythm disorders that require the implantation of artificial pacemakers.
Our hearts are always exercising, even when our bodies are at rest, and automatically pump harder and faster during strenuous activity. In a healthy heart, a specialized group of cells in the wall of the right atrium called the sinoatrial node (SA node) spontaneously produce electrical impulses that travel through the organ's conduction system to make it contract regularly. Thus, the SA node acts as the body's natural pacemaker, setting the rhythm of a normal beat.
Malfunctions in the SA node's electrical signaling network can lead to abnormal conditions such as sick sinus syndrome, a too-slow or irregular heartbeat, which are typically treated by installing an artificial, permanent pacemaker. SA node problems are more common in the elderly as the cardiac system's conductive network scars and degenerates with age.
The dearth of research regarding cardiac pacemaking using human cells has precluded the development of a next-generation, device-free, and more cost-efficient treatment that may replace the artificial electrical pacemaker implantation.
While most research in this area has used animal heart cells, this team used human sinoatrial nodal pacemaker cells (SANC) from donated heart tissue. They found that a calcium (Ca 2+) clock was coupled to the SANC's natural surface membrane molecules' electric producing clock (M clock).
This work unveils the complex and highly interdependent mechanisms of the heartbeat and shows promise for new cellular-level therapeutic targets that could someday offer alternatives to artificial pacemaker treatment in people with heart rhythm disorders.

Moderately paced 5 mile hike with 950 ft elevation gain to the top for great multi-Valley views at one of the highest peaks in the Santa Monica Mtns. Wonderful rock formations and flowers; waterfalls after rains, too! Meet 8:00 AM at trailhead on Mulholland Hwy. From 101 Ventura Fwy take Valley Circle/Mulholland Dr exit south, turn right on Valmar Rd (becomes Old Topanga Cyn Rd), right on Mulholland Hwy for 1.5 mi., park on dirt shoulder on left. Bring water, snack, lugsoles, hat, sunscreen. Leaders: Heidi Lennartz, Richard Shamban
This article will walk you through the process of understanding and utilizing the walking pace data provided by your Fitbit Versa. We will guide you through how to use this valuable information, what it means for your health, and what personalized fitness goals you can set. You must step it up to the next level if you want to keep up with your fitness tracking.
Tracking Your Progress: What sets Fitbit Versa apart is its ability to track your walking pace consistently over time. You can review your historical data, observe trends, and gauge your progress. This feature is invaluable for those striving to boost their fitness levels. Are you getting faster, maintaining a steady pace, or slowing down? Fitbit Versa will tell you, empowering you to adjust your fitness routine accordingly.
Average Pace: Your Fitbit Versa diligently calculates your average pace, which is the total distance covered divided by the total time taken during your walk. This figure serves as a foundational metric, providing a baseline for your walking performance. A slower average pace may indicate a leisurely stroll, while a brisk pace suggests a more vigorous walk. Understanding your average pace helps you gauge your overall walking speed.
Fitness Benchmark: Your average pace serves as a benchmark for your fitness level. It reflects how efficiently your body is moving, and tracking changes in this metric over time can indicate improvements in your cardiovascular health and muscular endurance. A lower average pace suggests a need to push yourself harder, while a consistent or increasing pace indicates progress.
Cardiovascular Health: A brisk yet manageable pace gets your heart pumping efficiently, promoting better cardiovascular health. It lowers the risk of heart disease, lowers blood pressure, and improves circulation.
Joint Health: Unlike high-impact exercises, walking is gentle on the joints. A healthy walking pace minimizes the risk of joint injuries and can even alleviate symptoms of conditions like osteoarthritis.
Progress Tracking: The Fitbit app syncs seamlessly with your device, offering detailed insights into your walking pace over time. You can monitor trends, track improvements, and celebrate milestones as you work towards a healthier pace.
Progressive Adjustments: As you become more comfortable with your current pace goals, consider gradually increasing them. This progressive approach ensures that you continue to challenge yourself and make steady fitness gains.
Listen to Your Body: Pay attention to how your body responds during your walks. If you find that your current pace is no longer challenging but comfortably sustainable, it may be time to set more ambitious goals.
In the pursuit of fitness, one of the most valuable tools at your disposal is the ability to analyze your walking pace progress over time. Your Fitbit Versa, renowned for its comprehensive tracking capabilities, offers you the means to do just that. By harnessing the insights it provides, you can monitor your improvements, set new goals, and stay motivated on your journey to better health.
Pace Data Breakdown: Your Fitbit Versa meticulously breaks down your walking pace data. It provides not only an overview of your average pace but also insights into split paces during your walks. This breakdown allows you to scrutinize your performance at different intervals.
Motivation: Tracking your walking pace progress can be immensely motivating. When you see tangible evidence of your improvements, such as a faster average pace or increased endurance, it reinforces your commitment to your fitness goals.
Identification of Plateaus: Monitoring your pace data may reveal plateaus in your progress. These periods where your improvements stagnate can be pivotal moments for adjusting your workout routines, exploring new walking routes, or consulting with a fitness expert for guidance.
Health Insights: Beyond fitness, analyzing your pace data can provide valuable health insights. Sudden drops in pace or unexpected variations may prompt you to consult a healthcare professional for a check-up, ensuring that you address any underlying health concerns.
Monitoring Intensity: The Fitbit Versa tracks your heart rate alongside your walking pace. By analyzing both metrics, you gain a deeper understanding of the intensity of your workouts. This data helps you stay within your target heart rate zone for optimal results.
Goal Achievement: Setting pace goals adds structure to your workouts. Whether you aim to maintain a brisk pace throughout your walk or incorporate interval training by varying your pace, your Fitbit Versa keeps you accountable and helps you achieve these goals.
Interval Training: Use your walking pace data to guide interval training. Alternate between periods of brisk walking and recovery at a slower pace. For example, walk at a moderate pace for three minutes, then increase to a brisk pace for one minute. Repeat this cycle throughout your walk to boost calorie burn and improve cardiovascular fitness.
Progressive Overload: As you become more fit, progressively challenge yourself by setting faster pace goals. Incrementally increasing your walking pace can lead to continuous improvement and prevent plateaus.
Customized Goals: Customize your pace goals based on your fitness objectives. If your aim is weight loss, consider setting a pace that maximizes fat burning. For endurance, aim for a steady pace that you can maintain for longer durations.
Track and Adjust: Regularly review your walking pace data and heart rate trends on the Fitbit app. If you notice consistent improvements, it may be time to adjust your pace goals upwards to keep pushing your limits.
Socialize and Compete: Connect with friends and family on the Fitbit platform to engage in friendly competitions and challenges. The social aspect can provide added motivation to keep walking and improving your pace.
